Pay less money for energy—and more attention to the environment.It’s pretty obvious, really. An efficient steam trap wastes less energy, which means you burn less fuel and reduce emissions. The results are energy savings and a cleaner, healthier environment. By helping companies manage energy, Armstrong steam traps are also helping protect the world we all share.

As a steam trap wears, it loses efficiency and begins to waste energy.But Armstrong inverted bucket traps last years longer than othertraps. They operate more efficiently longer because the invertedbucket is the most reliable steam trap operating principle known.

Clearly, the longer an efficient trap lasts, the more it reduces energywasted, fuel burned and pollutants released into the air. It’s an all-around positive situation that lets the environment win, too.Bringing energy down to earth in your facility could begin with arenewed focus on your steam system, especially your steam traps.Said another way: Zeroing in your steam traps is an easy way topay less money for energy—and more attention to the environment.

Companies around the world are beginning to realize that ratherthan being separate challenges, energy and the environment are and have always been a single mission. And that quality managementin one area will surely impact the other.

The Inverted Bucket Steam Trap

Resistance to damage from water hammerOpen bucket or float will not collapse as a result of water hammer.

Wear and corrosion resistanceFree-floating guided lever valve mechanismis “frictionless,” and all wear pointsare heavily reinforced. All working parts are stainless steel. Valve and seat are stainless steel, individually ground and lapped together in matched sets.

Continuous air and CO2 ventingVent in top of bucket provides continuous automatic air and CO2venting with no cooling lag or threat of air binding. Steam passing through vent is less than that required to compensate for radiation losses from the trap so it’s not wasted.

Excellent operation against back pressureSince trap operation is governed by the difference in density of steam and water, back pressure in the return line has no effect on the ability of the trap to open for condensate and close against steam.

Virtually no steam lossSteam does not reach the

water-sealed discharge valve.

Purging actionSnap opening of the valve

creates a momentary pressure drop and turbulence

in the unit drained. This breaksup films of condensate and air

and speeds their flow to the trap.

Dependable operationSimple, direct operation with

nothing to stick, bind or clog. Only two moving parts—

the valve lever and the bucket.

Freedom from dirt problemsCondensate flow under the bottom edge of

the bucket keeps sediment and sludge in suspension until it is discharged with the condensate. Valve orifice opens wide and closes tightly. No buildup of dirt or close

clearances to be affected by scale.

The inverted bucket is the most reliable steam trap operating principleknown. The heart of its simple design is a unique leverage systemthat multiplies the force provided by the bucket to open the valveagainst pressure. Since the bucket is open at the bottom, it resistsdamage from water hammer, and wear points are heavily reinforced forlong life.

The inverted bucket has only two moving parts—the valve leverassembly and the bucket. That means no fixed points, no complicatedlinkages. Nothing to stick, bind or clog.

Conserves Energy Even in the Presence of WearArmstrong inverted bucket steam traps open and close based onthe difference in density between condensate and steam—theinverted bucket principle. They open and close gently, minimizingwear. This simple fact means that inverted buckets are subject toless wear than some other types of traps.

In fact, as an Armstrong inverted bucket trap wears, its tight sealactually improves. The ball valve and seat of the Armstrong trapprovide essentially line contact—resulting in a tight seal becausethe entire closing force is concentrated on one narrow seating ring.

An Armstrong inverted bucket trap continues to operate efficientlywith use. Gradual wear slightly increases the diameter of the seatand alters the shape and diameter of the ball valve. But, as this occurs,a tight seal is still preserved—the ball merely seats itself deeper.

Corrosion-Resistant PartsThe stainless steel valve and seat of the Armstrong inverted bucketsteam trap are individually ground and lapped together in matchedsets. All other working parts are wear- and corrosion-resistantstainless steel.

Venting of Air and CO2

The Armstrong inverted bucket provides continuous automatic airand CO2 venting with no cooling lag or threat of air binding.

Operation Against Back PressureThe Armstrong inverted bucket has excellent performance against back pressure. It has no adverse effect on inverted bucketoperation other than to reduce its capacity by the low differential.The bucket simply requires less force to pull the valve open andcycle the trap.

Freedom From Dirt ProblemsArmstrong designed its inverted bucket to be virtually free of dirtproblems. The valve and seat are at the top of the trap, far awayfrom the larger particles of dirt, which fall to the bottom. Here theup-and-down action of the bucket pulverizes them. Since the valveof an inverted bucket is either fully closed or open, dirt particlespass freely. And the swift flow of condensate from under the bucket’s edge creates a unique self-scrubbing action that sweeps dirt out of the trap.

How to Use the IB Trap Summary Capacity Chart

ST-9

This catalog should be utilized as a guide for the installation andoperation of steam trapping equipment by experienced personnel.Selection or installation should always be accompanied by competenttechnical assistance or advice. Armstrong and its local representativesare available for consultation and technical assistance. We encourageyou to contact your Armstrong Representative for complete details.

The summary capacity chart plots actual trap capacity vs. inletpressure on a log-log grid. The trap capacities become straight lineson this grid. The small numbers along the pressure axis identify the subdivisions; for example, between the large 10 and 100, thenumbers 2, 3, 5, and 7 represent 20, 30, 50 and 70 psi.

The summary chart combines many trap families into one chart bypresenting only a portion of the capacity line for each orifice size.For charts that give capacity over a wide range of pressures, seethe specific trap model pages.

Individual capacity charts for various traps are given throughoutthis catalog. Those charts show capacity lines for each orifice, withpressures usually from 1 psi up to the maximum rated pressure ofthat orifice.

To select an inverted bucket steam trap using the summary capacitychart, you must know the condensate load, safety factor, inlet pressureand outlet pressure. Remember, the object is to select a trap thatcan 1) operate at the maximum inlet pressure, and 2) handle thecapacity at the minimum differential pressure. Consider the followingtypical problems.

Example 1. Constant pressure, condensing rate.Given:Maximum inlet pressure . . . . . . . . . . . . . . . . . . . . . . . . .70 psiNormal operating differential pressure . . . . . . . . . . . . . . .60 psiRequired capacity = 300 lb/hr condensate load times 3:1 safety factor, or . . . . . . . . . . . . . . . . . . . . . .900 lb/hr

Enter the chart at the 60 psi line and go up to 900 lb/hr capacity.This is directly on the 5/32'' orifice line for models 211, 811 and 881(and other traps). Now follow this line to the right, to the verticaldrop at 70 psi. This means the orifice will work, in these traps, upto a maximum differential of 70 psi. Assuming a cast iron trap issuitable, the 5/32'' orifice in a Model 211, 811 or 881 trap will meetall the operating requirements.

Example 2. Constant condensing rate but with possible reduced inlet pressure.Given:Maximum inlet pressure . . . . . . . . . . . . . . . . . . . . . . . .100 psiMinimum inlet pressure . . . . . . . . . . . . . . . . . . . . . . . . .40 psiRequired capacity = 400 lb/hr condensate load times 3:1 safety factor, or . . . . . . . . . . . . . . . . . . . .1,200 lb/hr

Consider the maximum operating pressure first. Enter the chart atthe 100 psi line and find the first capacity line above 1,200 lb/hr.This is the 5/32'' orifice in a Model 212, 812 or 882, and it has a capacity of 1,800 lb/hr at 100 psi. Now extend this straight line to the left until it intersects the 40 psi pressure line. At 40 psi, reada capacity of 1,300 lb/hr. (You could also refer to the individualcapacity charts for Models 212, 812 or 882.) Assuming cast iron issuitable, this is the desired trap selection to meet the requirementsof opening at the maximum pressure, and also having the neededcapacity at the minimum pressure.

This example points out how the capacity is influenced by the trapsize. Example 1 also used the same orifice size, but in a physicallysmaller trap. In the larger trap the same diameter orifice not onlyhas a higher capacity, it will work at higher pressures.

Example 3. Constant condensing rate but high back pressure.Given: Inlet pressure . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .100 psiNormal outlet (back) pressure . . . . . . . . . . . . . . . . . . . . .50 psiRequired capacity = 1,800 lb/hr condensate loadtimes 3:1 safety factor, or . . . . . . . . . . . . . . . . . . . .5,400 lb/hr

Traditional method:Since the differential pressure is only 50 psi, enter the chart at 50 psiand go up to a capacity of 5,400 lb/hr. This is just under the capacitylines for Models 214 and 814. However, the 5/16'' orifice is the largestorifice that will operate at 100 psi inlet pressure. (Remember thatthe back pressure may not always be there!) Extend the capacityline for the 5/16'' orifice to the left, and read a capacity of 4,800 lb/hrat 50 psi. Since this is too low, go up to the 215/815 capacity linesand repeat the process. The selection will end up being a Model 215or 815 with a 3/8'' orifice*.

About this chart ...The Armstrong capacity chart shows continuous discharge capacitiesof Armstrong traps under actual operating conditions, as determinedby many hundreds of tests made over the years. In these tests, hot condensate was used, at or near the steam temperature corresponding to the test pressure. The choking effect of flash steamin the orifice and the back pressure created by this flash steam weretherefore automatically taken into account. The test setups were similarto an actual installation hookup, so that pipe friction in both inlet anddischarge lines was reflected in the results.

* This method is conservative. While it will always select a workabletrap, it may select a larger trap than necessary. Consult ArmstrongApplication Engineering for further information about the effectsof back pressure.

200 Series Inverted Bucket Steam TrapsCast Iron for Vertical InstallationFor Pressures to 250 psig (17 bar)...Capacities to 20,000 lb/hr (9,072 kg/hr)

DescriptionThe most reliable steam trap known—the inverted bucket—provides efficientcondensate drainage of virtually all types of steam-using equipment. Put theinverted bucket to work in a tough cast iron package, and you have the bestof both worlds. Because they operate efficiently for longer periods of time,Armstrong cast iron inverted buckets add solid energy savings to lowerreplacement/labor costs.

A unique leverage system multiplies the force provided by the bucket to openthe valve against system pressure. The mechanism is free-floating, and hasno fixed pivots to create wear or friction.

Because the mechanism is located at the top of the trap, no dirt can collecton the orifice. Small particles of dirt are held in suspension until dischargedby the full differential purging action when the bucket sinks, pulling the valveoff the seat.

The discharge orifice is surrounded by a water seal, preventing live steamloss. Automatic air venting is provided by a small vent hole in the bucket, whichprovides continuous automatic air and CO2 venting at steam temperature.

Inverted bucket traps drain continuously, although discharging intermittently,allowing no condensate backup. They are also resistant to water hammer.

DescriptionArmstrong Model 411G vertical installation and Model 421 horizontal installationoffer smaller capacities at higher pressures.

A unique leverage system multiplies the force provided by the bucket to openthe valve against system pressure. The mechanism is free-floating and hasno fixed pivots to create wear or friction.


The discharge orifice is surrounded by a water seal, preventing live steamloss. Automatic air venting is provided by a small vent hole in the bucket.

Inverted bucket traps drain continuously to prevent condensate backup.They are also resistant to water hammer.

Model 421 adds the convenience and savings of in-line repairability and isdesigned to meet today’s energy-management requirements efficiently andeconomically over a long, trouble-free service life.

DescriptionArmstrong offers its 400 Series forged chrome-moly steel traps for verticalinstallation with a choice of screwed, socketweld or flanged connections.



The discharge orifice is surrounded by a water seal, preventing live steamloss. Automatic air venting is provided by a small vent hole in the bucket.This provides continuous automatic air and CO2 venting at steam temperature.

Inverted bucket traps drain continuously to prevent condensate backup.They are also resistant to water hammer.

Operation on Superheat. A normally operating bucket trap is filled with saturated steam and condensate. Superheated steam can enter only as fastas the steam inside can condense. As a result, the temperature of the trap isat (or slightly below) saturated steam temperature, regardless of the degreeof superheat.

Trap Selection. The pressure-containing parts of the steam trap should safelywithstand the maximum pressure and temperature conditions of the system.For example, a trap is required for a 900 psig (62 bar) main at 900°F (482°C).The normal operating temperature of the trap will be about 532°F (278°C).A Model 415 trap should be selected, even though several smaller traps arecapable of handling the working pressure.

For Superheat Service:1. Don’t oversize the orifice; a restricted orifice may be advisable.2. Specify a burnished valve and seat and an extended inlet tube

and check valve.3. Provide a drip leg of adequate diameter and length.4. Provide a generous length (2'-3') of inlet piping, with the trap

below the main.5. Don’t insulate the trap or the inlet piping.

DescriptionArmstrong’s 401-SH/501-SH Series inverted bucket steam trap line is made for overcoming the difficult combination of superheat and highpressure/low load service.

To survive this most severe steam service, Armstrong created an invertedbucket trap with a unique accumulation chamber. The chamber collects sufficient condensate to ensure full discharge cycles. A cup in the chamberfloats up and down on the steam inlet tube, sealing it off as the condensatelevel rises. At the same time as the chamber collects condensate, steam continues to flow under the bucket, making sure that the discharge valve closes tightly until the condensate rises into the trap body and the bucket falls down. The operation is on/off, no throttling or dribbling.

Furthermore, it combines all the advantages of an inverted bucket steam trap:

• High resistance to wear, corrosion and water hammer with no gaskets.• A unique leverage system multiplies the force provided by the bucket,

to open the valve against system pressure.• The mechanism is located at the top. No dirt can collect on the orifice.

Small particles of dirt will be held in suspension until discharged by the fulldifferential purging action.

• The discharge orifice is surrounded by a water seal, preventing live steamloss. Automatic air venting is provided by a small hole in the bucket.

• Inverted bucket traps require no adjustment. They do not allow condensatebackup and are resistant to water hammer.

Installation RecommendationsWhat little condensate there is on superheat and high pressure/low loadservice usually forms in drip legs and in the traps themselves. Thereforeproper piping and drip legs of adequate size and diameter are essential for the successful operation of the Armstrong superheat trap.

Drip Leg SizingThe properly sized drip leg will capture condensate. Too small a drip leg can actuallycause a venturi “piccolo” effect where pressure drop pulls condensate out of the dripleg and trap.

DH

M

Trap Draining Drip Leg on Steam Main

Cycling—Discharge Valve Wide OpenWith the steam feed tube to the trap chambersealed, condensate flows through the condensate feed tube (from accumulationchamber) into the trap chamber. Thissinks the inverted bucket, which opens the discharge valve, cycling the trap.

Cycle EndingAs the level of condensate in the accu-mulation chamber falls, the cup sealingthe steam feed tube moves downward,opening a passage for steam to flowinto trap chamber.

Trap ClosedAs steam begins to flow through the accumulation chamber and up the steam feed tube under the invertedbucket in the trap chamber, the discharge valve closes tightly.

Cycle About to RepeatAs the level of condensate rises in theaccumulation chamber, the cup floatsup until it again seals the steam feedtube, and the cycle repeats.

DescriptionArmstrong offers its 5000 Series forged chrome-moly steel traps for verticalinstallation with a choice of screwed, socketweld or flanged connections.



The discharge orifice is surrounded by a water seal, preventing live steam loss.Automatic air venting is provided by a small vent hole in the bucket. This providescontinuous automatic air and CO2 venting at steam temperature.

Inverted bucket traps drain continuously, although discharging intermittently,to prevent condensate backup. They are also resistant to water hammer.

Operation on Superheat. A normally operating bucket trap is filled with saturated steam and condensate. Superheated steam can enter only as fastas the steam inside can condense. As a result, the temperature of the trap is at (or slightly below) saturated steam temperature, regardless of the degreeof superheat.

Trap Selection. The pressure-containing parts of the steam trap should safelywithstand the maximum pressure and temperature conditions of the system.For example, a trap is required for a 1,000 psig (68 bar) main at 950°F(510°C). The normal operating temperature of the trap will be about 546°F(286°C). A Model 5133G trap should be selected, even though several smallertraps are capable of handling the working pressure.

For Superheat Service:1. Don’t oversize the orifice; a restricted orifice may be advisable.2. Specify a burnished valve and seat and an extended inlet tube and

check valve.3. Provide a drip leg of adequate diameter and length.4. Provide a generous length (2'-3') of inlet piping, with the trap below the main.5. Don’t insulate the trap or the inlet piping.

2000 Series Stainless Steel Traps

Wear and corrosion resistanceFree-floating guided lever valve mechanism is “frictionless,” and all wear points are heavily reinforced. All working parts are stainless steel. Valve and seat are stainless steel, individually ground and lapped together in matched sets.

Continuous air and CO2 ventingVent in top of bucket provides continuous automatic

air and CO2 venting with no cooling lag or threat ofair binding. Steam passing through vent is less than

that required to compensate for radiation lossesfrom the trap, so it’s not wasted.

Purging actionSnap opening of the valve creates a momentary pressure drop and turbulence in the unit drained. This breaks up films of condensateand air and speeds their flow to the trap.

Virtually no steam lossSteam does not reach the water-sealed discharge valve.

Dependable operationSimple, direct operation with

nothing to stick, bind or clog. Only two moving parts—

the valve lever and the bucket.

Excellent operation against back pressureSince trap operation is governed by the difference in density of steam andwater, back pressure in the return line has no effect on the ability of the trap to open for condensate and close against steam.

Freedom from dirt problemsCondensate flow under the bottom edge of

the bucket keeps sediment and sludge in suspension until it is discharged with the condensate. Valve orifice opens wide and

closes tightly. No buildup of dirt or close clearances to be affected by scale.Resistance to damage from water hammer

Open bucket or float will not collapse as a result of water hammer.

360° universal 304 stainless steel connector Provides quick, easy in-line renewability along with all the proven advantages

of an inverted bucket operation. Also available with optional IS-2 integral strainer connector with 20 x 20 mesh stainless steel strainer.

Sealed, tamperproof 304-Lstainless steel package Able to withstand freeze-upswithout damage.

The Armstrong stainless steel traps—Series 1000, Series U-1000,Series 1800 and Series 2000—have high resistance to damage fromfreeze-ups. They also offer high resistance to wear and corrosion forlonger service reliability, and they provide continuous air venting.

Armstrong stainless steel traps provide maximum ease and economyof installation, inspection or replacement. What’s more, an Armstrongstainless steel trap is the ideal solution for trapping applications suchas tracer lines, steam mains, and heating and processing applications.

20-DC Series Automatic Differential Condensate ControllersFor Pressures to 250 psig (17 bar)...Capacities to 20,000 lb/hr (9,072 kg/hr)

A

C

B

L

DescriptionArmstrong automatic differential condensate controllers (DC) are designed to function on applications where condensate must be lifted from a drain point or in gravity drainage applications where increased velocity will aid incondensate drainage.

When lifting from the drain point, often referred to as syphon drainage, thereduction in pressure that occurs when the condensate is elevated causes a portion of it to flash back into steam.

Ordinary steam traps, unable to differentiate between flash steam and livesteam, close and impede drainage. Increased velocity with gravity drainagewill aid in drawing the condensate and air to the DC. This increased velocity iscaused by an internal steam by-pass, controlled by a manual metering valve,so the condensate controller will automatically vent the by-pass or secondary steam. This is then directed to the condensate return line or collected for use in other heat exchangers.

Ordinary steam traps, unable to differentiate between flash steam and livesteam, close and impede drainage. Increased velocity with gravity drainagewill aid in drawing the condensate and air to the DC. This increased velocity iscaused by an internal steam by-pass, controlled by a manual metering valve,so the condensate controller will automatically vent the by-pass or secondary steam. This is then directed to the condensate return line or collected for use in other heat exchangers.

Float & Thermostatic Steam Trap

Corrosion resistanceEntire float mechanism is made of stainlesssteel. The float is Heliarc welded to avoid theintroduction of dissimilar metals, which couldlead to galvanic corrosion and float failure.

No water seal at inlet Inlet high on body and condensate dischargevalve in the bottom of the body prevent formationof a water seal that could block flow of air tovent under very low pressure conditions.

Optional integral vacuum breakersProvide maximum protection against freezingand water hammer in condensing equipmentunder modulated control. They also eliminate

another fitting being installed in the line.

Long life and dependable service Valve is stainless steel in all sizes. Seat is heat treated in 1-1/2" pipe size and larger. Rugged float mechanism is built to resist wear, and the stainless steel float provides exceptionally high collapsing pressure and resistance to hydraulic shock.

Operation against back pressure Trap operation is governed solely by the condensate level in the trap. Back pressure in the return line will not render the trap inoperative as long as there is any pressure differential to force condensate through the discharge valve.

Continuous drainage No pressure fluctuations due tointermittent condensate drainage.Condensate is discharged at very close to steam temperature. No priming needed.

High-capacity venting of air and C02

Built-in thermostatic air ventdischarges large volumes of air

and C02 through its separate orifice—even under very low

pressure conditions.

Water sealed valve Steam cannot reach

condensate discharge valvebecause it is always under

water. Balanced pressure thermostatic air vent closes on

steam at any pressure within the operating range of the trap.

When steam pressure may vary from maximum steam supply pressure to vacuum, Armstrong F&Ts are your most energy-efficientchoice. Our line of F&Ts brings Armstrong performance, dependabilityand long life to trapping services requiring continuous drainage withhigh air venting capacity. Thanks to separate orifices for condensateand air, they provide continuous condensate drainage and air venting—even under conditions of zero pressure.

All the benefits detailed below have been designed into Armstrong F&Ts through long experience in the manufacture of pressure float-type drain traps. They assure you of optimum operating efficiency for long periods with minimum trouble.

The More Your Steam Pressure Varies, the More You Need Armstrong F&T Traps

Armstrong float and thermostatic traps are unique in their superheavy duty construction. Armstrong uses high quality ASTM A48Class 30 cast iron or ASTM A216 WCB cast steel—normally found in pressure vessels rated to 250 psi or 465 psi. Internal mechanismsare made from stainless steel and are heavily reinforced. No brasscotter pins here. Valves and seats are stainless steel, hardened,ground and lapped to withstand the erosive forces of flashing condensate.

Why go to all this trouble on traps normally recommended for low-pressure, modulating service? The answer is in the word modulating. Modulating pressures mean widely varying loads, thermal cycling and high air and non-condensable gas loads.

In other words, tough service. Inferior, lightweight construction is amistake waiting to happen. Trap failures on modulating pressure maylead to water hammer, corrosion and even heat exchanger damage.

Armstrong’s published capacities are based on actual measurementsof traps handling hot, flashing condensate. Competitive F&Ts may utilizetheoretical calculated capacities. Armstrong uses its own steam labto give you actual capacity—especially important on high-capacitytraps such as those in our ultra-capacity line. Not only does Armstrongoffer super heavy duty construction for long life and reliability, but we also supply the data to back up performance. Here’s a simple,easy-to-remember summary: The more your pressure varies, themore you need Armstrong F&Ts.

DescriptionArmstrong B and BI Series F&T traps combine high standards of performance and long life with economy for heating service where continuousdrainage with high air-venting capacity is required.

Because of the wide use of vacuum returns in systems of this type, the thermostatic air vent element is charged to give it the capability of compen-sated response to the pressure-temperature curve of steam at any pressurefrom less than 20'' (500 mm) Hg vacuum to 30 psig (2 bar) gauge. B and BISeries F&T traps will vent air at slightly below steam temperature throughoutthis entire range of operation.

All B Series traps, except the 1/2'' (15 mm) and 3/4'' (20 mm), have inlet connections on both sides of the body to provide flexibility in piping. The BI Series F&T traps in sizes 1/2'', 3/4'' and 1'' feature the convenience of in-line connections with the same internals as the B Series.

The condensate controller (CC) configuration was developedespecially to meet very large capacity needs in applications where condensatemust be lifted from the drain point to the trap. Under such conditions—oftenreferred to as syphon drainage—the reduction in pressure that occurs whenthe condensate is elevated causes a portion of the condensate to flash intosteam. Ordinary traps, unable to differentiate between flash steam and livesteam, close and impede drainage.

LS & MS Series Ultra-Capacity Float & Thermostatic Steam TrapCast Steel for Horizontal Installation, With Thermostatic Air VentFor Pressures to 450 psig (31 bar)...Capacities to 280,000 lb/hr (127,000 kg/hr)

DescriptionThe simple yet rugged cast steel construction of the LS & MS Series Ultra-Capacity F&T steam traps offers long, trouble-free service. All floats, valvesand seats, and lever mechanisms are constructed of stainless steel.

The integral thermostatic air vent is a balanced-pressure phosphor bronzebellows caged in stainless steel. It is designed especially for heavy-dutyindustrial applications where highly efficient, uninterrupted service is essential.This balanced-pressure air vent will respond to the pressure-temperaturecurve of steam at any pressure from zero to 250 psig (17 bar). Thus—up to 250 psig (17 bar)—air is vented at slightly below steam temperature.


Model LS: 450 psig @ 650°F (31 bar @ 338°C)Model MS: 450 psig @ 650°F (31 bar @ 338°C)

Maximum operating pressure:Model 30-LS: 30 psig (2 bar) saturated steamModel 100-LS: 100 psig (7 bar) saturated steamModel 150-LS: 150 psig (10 bar) saturated steamModel 250-LS: 250 psig (17 bar) saturated steamModel 250-MS: 250 psig (17 bar) saturated steamModel 450-LS: 450 psig (31 bar) saturated steamModel 450-MS: 450 psig (31 bar) saturated steam

Maximum operating temperature bellows: 422°F (217°C)NOTE: For pressures above 250 psig (17 bar), the thermostatic vent shouldbe removed and only a CC or LD version should be used.

SpecificationFloat and thermostatic steam trap, type ... in cast steel, with thermostatic air vent.


How to Order

Special ConfigurationsCondensate controller with flash release for syphon drainage and/orcascade service. The condensate controller (CC) configuration was developedespecially to meet very large capacity needs in applications where condensatemust be lifted from the drain point to the trap. Under such conditions—oftenreferred to as syphon drainage—the reduction in pressure that occurs whencondensate is elevated causes a portion of the condensate to flash intosteam. Ordinary traps, unable to differentiate between flash steam and livesteam, close and impede drainage.

The LS & MS Series condensate controllers (CC) are equipped with a fixed,restricted orifice near the top of the body to bleed off the flash steam (and all air present). This permits the trap to function properly on condensate.

Liquid drainer with back vent for exceptionally high capacity drainage ofliquid from gas under pressure. The liquid drainer (LD) configuration wasdeveloped to meet very large capacity needs in draining water and other liquidsfrom air or other gases under pressure. To prevent air or gas binding, theaccess port in the top of the body serves as a back vent connection to theequipment being drained. For capacity data, see pages LD-30 and LD-49 orconsult your Armstrong Representative.

TVS 800 Series Cast Iron Trap Valve Station

The Innovation Is IntegrationThe Armstrong TVS makes what used to be long, complicated steaminstallation stories simple and compact. It shortens installations byintegrating components—specifically an inverted bucket steam trapwith two or more valves.

For example, here’s an old description for a typical installation:valve-nipple-strainer-nipple-trap-nipple-valve. It’s a long tale, even for this simple piping arrangement. The Trap Valve Station rewrites

this steam story: pipe-TVS-pipe. In other words, the TVS makes it all one, delivering the functions of multiple components in a dramatically smaller unit. It integrates two high-value products in a package of revolutionary versatility.

Look above to see how the Armstrong cast iron Trap Valve Station has rewritten these typical steam installations.

TVS Series Stainless Steel Trap Valve StationThe Piston Valve

• Dual sealing actionThe piston valve is a seatless valve that includes two graphite andstainless steel valve sealing rings that seal the stem and functionas a valve seat. This combination provides long-term protectionagainst leaks to the atmosphere and downstream piping.

• Self-cleaning action Stainless steel piston slides without rotating between the twovalve sealing rings, preventing dirt from damaging the sealingsurfaces.

• Sealing integrityFlexible disc springs automatically provide leak tightness by exertingpressure which keeps the upper and lower valve sealing rings com-pressed at all times. Sealing tightness is assured by the compressionof the sealing rings against the piston and the valve body. This

combination of disc springs and dual valve seal rings protectsagainst expansion and contraction due to heating and cooling.This assures dependable operation, even after years of service.

• Protected valve stem The valve stem and sealing surfaces are completely protectedfrom dirt and corrosion by the stem cap, whether in an open orclosed position.

• In-line repairability All valve components may be easily replaced in-line.

• Long-term operationPiston valve design assures actuation even after many years without operation.

Inlet Test Valve becomes fourvalves in oneStart-up Valve—enables drip/tracer lines to heat up quicker on start-up.

By-pass Valve—allows drip/tracer lines to stay in operation if trap replacement is necessary.

Drain Valve—drains condensate out of thedrip/tracer line at the end of the season.

Steam Isolation Valve—isolates a steam trapfor repair or replacement. Corrosion resistant

All stainless steel materials maximize corrosionresistance and increase valve and trap life.

Testing accuracyTest port provides more accurate

picture of trap operation than listening or temperature devices.

Easy opening valvesCorrosion-resistant stainless steelhandle offers increased leverage for easy opening. Safety handles are standard. Lever handles shown.

TVS Makes a Long Story … ShortThe Armstrong stainless steel inverted bucket steam trap simplycarries a good idea to its logical conclusion by sealing all theproven IB advantages in a tamperproof, corrosion-resistant package. Lightweight and compact, Armstrong inverted bucketscan withstand freeze-ups without damage. In fact, we’re so sure oftheir performance we guarantee them for three years against leaks.

With the introduction of the 360° standard connector several years ago and more recently the IS-2 connector with integralstrainer, Armstrong added even greater utility to this stainless steel workhorse. The universal connector made it possible toinstall inverted bucket efficiency and long service life in any piping configuration with little or no repiping.

TVS: New Role for the ConnectorNow the concept of the Trap Valve Station gives the universal connector another job: matchmaker. It brings together a stainlesssteel inverted bucket steam trap and plug valves.

Armstrong also gives you another way to combine steam traps andvalves. The plug valve TVS 2000 integrates stainless steel invertedbucket traps and plug valves into preassembled trap test units. Thenet result? Reduced purchasing and design time, lower installationcosts and savings in piping space. Plus the energy savings that aredividends of regular trap testing.

Test … and SaveSteam trap testing is a well-accepted component of aggressiveenergy management. Certainly, it’s essential to the efficiency of a well-designed and properly maintained steam system.

Consider this example: A 1/8" (3.2 mm) orifice leaking 45 lb (20.4 kg)of steam per hour at 100 psi (6.9 bar) will squander $2,102 worth of energy in one year, assuming a steam cost of $5.00/1,000 lb(450 kg). Numbers like these make it easy to see the importance of reliable trap monitoring.

Most experts agree that testing steam traps with test valves is themost reliable of available methods because it permits you to checktrap discharge visually. With test valves you can see evidence oftrap failure that is difficult to detect with other test methods. Andthe quicker you see what you may be missing now, the quicker you can begin saving the precious energy failed traps waste.

Simplification. That’s the greatest contribution of the TVS to routine trap testing. Installation is simpler. Maintenance is simpler.And regular testing is simpler.

DescriptionArmstrong offers three thermostatic wafer steam traps. The WT-1 is ideal for low-capacity steam tracers and features an exclusive non-welded waferdesign and internal strainer screen two to three times larger than that of other thermostatic traps in a sealed stainless steel body. Choice of NPT or BSPT screwed connections.

The WT-2000 does not have an internal strainer, but is equipped with a special360° connector to expand piping options and simplify installation. Choice ofNPT or BSPT screwed connections, or socketweld connections. Also availablewith optional IS-2 stainless steel connector with integral strainer.

Armstrong’s WT-3 is a carbon steel thermostatic wafer trap for superheateddrip service. It features an exclusive non-welded wafer design, which eliminatesproblems associated with weld stress. The WT-3 has no thin-walled enclosuressuch as bellows or welded diaphragms. It is also resistant to water hammer.Choice of NPT or BSPT screwed connections, or socketweld connections.

NOTE: Since the normal operation of all suppressed temperature-discharge(subcooling) steam traps is to back up condensate, they should not be used on drip legs for saturated steam service, heating or process equipment.Exercise care in the maintenance of any thermostatic wafer trap with a smalldischarge area susceptible to clogging.

DescriptionSH Series superheat steam traps operate by the effect that rising temperaturehas on the thermostatic bimetallic elements.

At start-up the valve is wide open, which allows a large volume of non-condensables and cold condensate to be removed from the system. Whenthe system reaches steam temperature, the elements become sufficiently hot to pull on the trap’s valve stem, closing the valve.

The valve remains closed until the bimetallic elements cool, thus allowing the valve to crack open, vent the condensate and non-condensables, andthen close again when steam temperature is reached.

The SH Series superheat steam traps adjust automatically to changing conditions.Hot elements in the valve generate forces to offset rises in pressure.

SpecificationArmstrong bimetallic style steam traps in carbon steel (Model SH-250) orstainless steel (Model SH-900) with integral stainless steel strainer, inlinerepairable. The mechanism shall consist of a stacked nickel-chrome bimetaloperator (SH-250 nickel plated) with titanium valve and seat (SH-250 boronizedvalve and seat). The steam trap shall be capable of operation on low-loadapplications throughout its pressure/temperature range.

The Armstrong TAVB is a combination thermostatic air vent/vacuum breakerthat is ideally suited for steam-filled vessels with modulating controls. The TAVBwill vent air and other non-condensables from vessels such as shell and tubeheat exchangers, jacketed kettles and steam coils during their operation. It willalso break the vacuum that forms during steam control modulation.

This balanced pressure air vent responds to the pressure-temperature curveof steam, and the soft-seated vacuum breaker responds to 2" H2O of vacuum.

Features• Maximum allowable pressure: 300 psig (20 bar)• Maximum allowable temperature: 365°F (185°C)• Maximum working pressure: 150 psig (10 bar)• All stainless steel welded construction• NPT connections

Armstrong thermostatic air vents should be installed at the highest point on asteam chamber, with the air vent located above the chamber. This will minimizethe possibility of any liquid carryover, and air can be vented to atmospherewithout a drain line.

Armstrong Simplifies Your Tracing Line SystemsDesigned to simplify and supply all the components (steamtraps, manifolds, valves, etc.) necessary for your drip andtracer line applications, Armstrong’s new Steam Distributionand Condensate Collection Manifolds bring all componentstogether to reduce installation costs and provide a compact,easily accessible, centrally located assembly.

Armstrong’s manifold series includes four different configurations, a Steam Distribution (MSD/SMSD), and aCondensate Collection Assembly (CCA/CCAF). As an option,the condensate manifolds can offer freeze protection.

In either case, you will save the expensive headaches of trying to fabricate in-house. What’s more, your manifold will be backed by the famous Armstrong quality—and a standardthree-year limited warranty.

Steam Distribution ManifoldsAs a Steam Distribution Assembly (MSD/SMSD), the manifoldplaces all steam supply valves in one location. Standardizingcomponents and centralizing their location simplifies installation,cutting costs from the beginning. You also save becauseroutine maintenance is faster.

Condensate Collection ManifoldsTo make industry’s trapping and valving more efficient,Armstrong combines its stainless steel steam trap valve stations with manifolds into a package called the CondensateCollection Assembly (CCA). This prepackaged assembly offersmany great benefits—cost savings in installation, designflexibility, and reduced purchasing time. CCAF would alsoinclude syphon tube freeze protection.

Whatever your condensate collection or steam distributionneeds, Armstrong has the manifold for savings over the long term.


ST-91

Shown are typical locations forArmstrong manifolds. The many manifolds in chemical/petrochemicalplants consume valuable floor spaceand often block movement among the units. Operating costs are high, andinstallation requires expensive customfabrication on site. Clearly, a prefabricatedmanifold permitting standardization ofcomponents offers substantial savingsover conventional units. Shaded products are available from Armstrong.Call or consult your ArmstrongRepresentative if additional productdetails are required.

The Proof Is in the PistonMany of Armstrong’s manifolds utilize the piston valvebecause of its years of excellent performance in steam systems all over the world. The proof of Armstrong’s longservice life for manifolds…is in the piston.

All types of valves—plug valves, gate valves, piston valvesand even ball valves—have been summoned for duty insteam service. Due to its excellent sealing characteristics in steam service, and because it has no gland packing, the piston valve is frequently selected for steam systems.

People who have used it over the past 90 years can testifythat leakage to atmosphere is extremely rare, even withoutany maintenance. The elastic contact between piston andvalve sealing rings provides a perfect tightness, both in-lineand to atmosphere.

Steam system valves, whatever their design, are used toisolate steam and condensate lines or when a faulty steamtrap needs to be removed from the line. This means the valvesstay in the open position for long periods and are nearlyalways in contact with the atmosphere. It is not surprising,therefore, that when the valves need to be closed, they canoften prove difficult to operate. Our experience and thedemands from end users for energy efficiency have led usto a sealing system designed especially for steam service.

• Dual sealing action. The piston valve is a seatless valvethat includes two graphite and stainless steel valve sealingrings that seal the stem and function as a seat. This combination provides long-term protection against leaksto the atmosphere and downstream piping.

• Self-cleaning action. Stainless steel piston slides withoutrotating between the two valve sealing rings, preventingdirt from damaging the surfaces.

• Sealing integrity. Flexible disc springs automatically provide leak tightness by exerting pressure, which keepsthe upper and lower valve sealing rings compressed at alltimes. Sealing tightness is ensured by the compression of the sealing rings against the piston and valve body.

This combination of disc springs and dual valve seal ringsprotects against expansion and contraction due to heatingand cooling. This ensures dependable operation, even afteryears of service.

• Protected valve stem. The valve stem and sealing surfacesare completely protected from dirt and corrosion by the stemcap, whether in an open or closed position.

• In-line repairability. All sealing valve components may beeasily replaced in-line.

• Long-term operation. Piston valve design ensures actuationeven after many years without operation.

Pre-Assembled… Condensate Collection Assembly (CCA)Armstrong combines its Trap Valve Stations (TVS) with manifolds into a package called the Condensate CollectionAssembly (CCA). This prepackaged assembly offers manygreat benefits—cost savings in assembly, design flexibilityand reduced purchasing and design time. The CCA withTVS 4000 and 2000 Series Inverted Bucket Traps is guaranteed for 3 years.

Cost SavingsThis preassembled concept offers tremendous savings byreducing multiple component purchases that cause additionalpurchase order monitoring and shipping costs. Other savingsinclude far less labor time required for field assembly.

This modular forged steel body design provides quickassembly/delivery, reducing overall project costs.

• Eliminates multiple component purchases• Reduced design specification costs• Prefabrication vs. field assembly for easy installation• Reduced shipping and field handling costs• Lower long-term maintenance and operating costs• 3-year guarantee

Design FlexibilityArmstrong can meet virtually any design parameter withyour choice of socketweld or threaded connections. Invertedbucket, thermostatic, thermostatic wafer or disc steam trapscan be provided. If you require a specific piping arrangement,Armstrong can offer the flexibility to meet your specifications.

• Most Armstrong steam trap types• Various Trap Valve Station options:

- TVS 2000- TVS 4000

• Dimensional consistency• Space savings• Freeze protection option• Insulation package available

MaterialsManifold body: ASTM A105 forged steel

Freeze Protection Package (CCAF)–OptionalA manifold assembly for more efficient condensate returnhas another benefit—freeze protection. Armstrong’s innovative manifold design actually serves as a heat station,heating one or more traps if the steam supply is interruptedor shut off to the traps. The protection is accomplished aslong as one trap continues to discharge into the manifold.The manifold’s internal syphon tube creates a water seal,which contains the flash steam from the discharge of thelive trap. This allows radiant heat to protect shut-off trapsfrom freezing.

An optional freeze protection valve package senses condensate temperature. When this device opens, it drainscondensate from the manifold assembly, thus providing further freeze protection.

Thermic Vent BucketsWhenever steam is turned on and off, air will accumulate in the piping andsteam equipment. A trap equipped with a thermic bucket will discharge this air50 to 100 times faster than a standard bucket, reducing warm-up time. Thermicvent buckets are suitable for pressures up to 130 psig (9 bar). A large venthole in the bucket can also solve air venting problems upon start-up.

Internal Check Valves—1/2'' (15 mm) Thru 2'' (50 mm) NPTAlmost all Armstrong inverted bucket steam traps can be equipped with internalcheck valves. A check valve is needed between the trap and the equipmentbeing drained in the following cases:• When the trap is installed above the unit drained• When sudden pressure drops may occur in the steam supply to the unit• Whenever a back pressure exists in the condensate return line

Armstrong spring-loaded, stainless-steel internal check valves can be screweddirectly into the trap inlet or into an extended inlet tube having a pipe couplingat the top.

“In-Line” Check Valve—1/2'' (15 mm) and 3/4'' (20 mm) NPTOn 1800 and 2000 Series stainless-steel traps, an internal check valve cannotbe installed. Armstrong’s CVI “in-line” check valve will solve the problem.

Pop Drain for Freeze ProtectionIn general, a properly selected and installed Armstrong trap will not freeze as long as steam is coming to the trap. If the steam supply is shut off, a popdrain should be used to automatically drain the trap.


Thermo DrainsThermo Drains are installed in a Tee ahead of 200 Series traps or replace the drain plug directly in the body of specially machined 800 Series traps. Inlet tubes are removed. When steam supply is shut off and temperature drops to 165°F (74°C), the thermal element opens the drain valve and empties the trap body. Not recommended for service above 15 psig (1 bar).

For maximum protection against freezing and water hammer in heating coilsunder modulated control, for example, vacuum breakers are recommended in conjunction with freeze protection devices.

Dirt ProblemsWhenever dirt plugs the bucket vent, Armstrong recommends the use of a scrubbing wire which, on each cycle, keeps the bucket vent hole open.NOTE: On small size stainless-steel (only) bucket traps, a wiggle wire isinstalled as standard.

In normal conditions, the inverted bucket trap is not sensitive to dirt problems(because of its orifice at the top of the trap), unlike most other traps, whichshould be installed normally with a strainer (see Armstrong “Y” Type Strainerspage S-16).

Probe Connections are available for trap monitoring on most inverted buckettraps. Consult your Armstrong Factory Representative.

ConnectorsBesides 2000 Series stainless steel inverted bucket traps, the standard connector or IS-2 connector with integral strainer can also be used on TT-2000 thermostatic, WT-2000 thermostatic wafer and CD-3300 disc traps.

Keeps an Eye on Your Steam Traps 24 Hours a Day Every Day

“It’s like having a man sitting there watching traps all day.” That’show a maintenance supervisor at an installation summed up thebenefits of SteamEye.

But exactly how does SteamEye do what it does? And how does ituse radio waves to signal a real beginning in steam system optimization?What is radio frequency (RF) steam trap monitoring anyway?

Radio frequency monitoring of steam traps gives you an instantaneous insight into trap performance that is the most accurate measure of steam trap status available. The system consists of a transmitter that is threaded into an inverted bucket or F&T* steam trap, a repeater (if necessary), a receiver and a personal computer. Building automation system integration is also an option. Consult your Armstrong Representative or Armstrong’sApplication Engineering Department.

SteamEye Saves Energy and MoneyWhoever first observed “Little things mean a lot” perhaps had failedsteam traps in mind. Show us a steam trap blowing through (losingsteam), and we’ll show you potential for huge savings in the dollarsyou spend for energy to generate steam in the first place. Besides,less energy consumed means less waste, fewer emissions and ahealthier environment.

As you see from the table below, a little steam leak can truly be the start of something big. A single trap with an 1/8-inch orifice cansquander more than $4,000 per year. Multiply that by the number of traps represented in a typical 20% failure rate, and you begin toget the idea. Failed steam traps waste energy and cost you money.Big money. But that was then. Now there’s SteamEye.

*NOTE: Transmitters can be installed on all float & thermostatic traps with a bottom drain connection and Armstrong inverted bucket steam traps with probe connections. Float & thermostatic transmitter will detect temperature only, not blow-thru.

Keeps an Eye on Your Steam Traps 24 Hours a Day Every Day

SteamEye literally keeps an eye on the steam component of a criticalprocess, alerting you instantly to a temperature reduction due to thebacking up of condensate, which could signal a process or productat risk.

• Permits using software to rank equipment as critical or non-criticalso you can prioritize repairs

• Reduces product loss and process downtime by quickly pinpointingproblems, enabling personnel to respond quickly

• Increases productivity by reducing downtime due to lack of propercondensate removal

If traps could talk, think of the stories they could tell you about energywaste and misplaced maintenance efforts. With SteamEye, traps cantalk. Ask your Armstrong Representative what they’re saying about:

• Increased personnel safety• Increased control over steam equipment• Measurable reductions in maintenance costs• Increased plant productivity• Reduced product loss• Improved profit potential

SteamEye Saves Time and Maintenance DollarsPerhaps your maintenance staff has been right-sized to a fraction of its former size. If so, you’ve joined the ranks of those who areexpected to do more with less. That’s why SteamEye can be aninvaluable partner in making the impossible a reality. An examplewill illustrate how.

Let’s say you have a trap population of 500. If you accept 20% as atypical failure rate, you have 100 bad traps. Let’s also assume thatyou can check 100 traps per day. But which 100 are bad? WithoutSteamEye, you simply don’t know. That means you have to test all500—and invest five days to accomplish a task you know shouldrequire only one day. The net loss in man-hours and maintenancedollars: five full days.

That was without SteamEye. With it, you will know instantly whichtraps have failed. So you won’t have to waste time and money sending manpower out to test working traps. What’s more, no onehas to be at the trap to test it. That improves safety and efficiency.Since SteamEye notifies you of failed traps as they fail, you’ll haveno backlog of trap repairs/replacements. Net gain in man-hours torepair/replace traps and do other maintenance activities: five full days.

SteamEye® Software Never SleepsWhile the transmitters, the receiver and a computer collectively makeup the body of the SteamEye monitoring system, the software is itsheart. It’s the SteamEye software that serves as the sentry who isalways on duty.

Think of the SteamEye software as the power and vision behind the whole system. It is the operational link that ties all of your equipment together to give you continuous monitoring. A remarkablediagnostic tool, the SteamEye will simultaneously put you in 20 or200—or more—places at the same time. For more details on thesoftware and the kind of data it provides, see page TM-4.

In this condition, the probe tip is making contactwith condensate, indicating the presence of condensate. If the temperature is above the predetermined set point, SteamEye would reportan OK condition.

Now the probe tip is exposed, and the trap temperature is above the predetermined set point.SteamEye would signal a loss of prime or a trapthat is allowing live steam to blow-thru (BT).

The trap is now flooded with condensate, andSteamEye would alert you to a cold trap as soonas the temperature fell below the predeterminedtemperature set point.

How can SteamEye know and communicate what’s happeninginside a steam trap? The answer is a probe that gives you a temperature/condensate profile of a trap in comparison to established parameters. A temperature sensor indicates when atrap’s internal temperature falls below a predetermined set point.

Since the probe is essentially a liquid-level monitoring device,absence of condensate in the inverted bucket steam trap indicatesa blow-thru or loss of prime. The job of the transmitter is to transmitthe data back to the receiver.

The transmitter sends a radio frequency signal indicating the statusof the steam trap back to the receiver. If the transmitter is out ofrange of the receiver, one or more repeaters send the signal back to the receiver. The receiver is connected to the communicationsport of a personal computer running the SteamEye monitoring program. Information regarding a steam trap’s operating condition (OK, blow-thru or cold) can be viewed with this program. The datacan then be downloaded into the optional APM Super+ program for additional reporting capabilities.

What is the typical range of the RF signal? In applications wherethe transmitter is located within the line of sight of the receiver, the range is approximately 400 yards. In facilities where the signal must travel through walls or floors, the range varies. The typicalrange of the signal is approximately 100 yards. If the receiver is out of the range of a transmitter, devices called repeaters can beplaced between the transmitter and the receiver to “repeat” the signal from one device to the next. A transmitter signal can passthrough up to seven repeaters. Since it is difficult to know the range of a transmitter in a facility, conduct a radio frequency signalstrength survey to determine if repeaters should be used and howmany will be required.

Let’s face it: At any given time a percentage of your traps have failedand you just don’t have the manpower to check them frequently.Besides, the trap you check on Tuesday afternoon may fail Wednesdaymorning—and not be scheduled for a recheck for months, even years.You just have to put up with a certain percentage of failure, right?Wrong. Not any more. That’s precisely the point of SteamEye.

As we have seen, the SteamEye software is your window into the inner workings of your steam trap population. You can also use the SteamEye software in conjunction with the optionalAPM Super+*. This program allows you to export and import thedata gathered by the SteamEye software and generate a variety ofreports. As a result, you can build a remarkably versatile databaseof trap operating history.

The SteamEye software allows you to identify traps as critical ornon-critical, as shown in Screens TM-1 and TM-2. Note the tabbedscreens across the top and the System Status profile on the leftside of Screen TM-1. Screen TM-2 summarizes faults on non-criticaltraps. Screen TM-3 gives you a good idea of the level of detail available through the SteamEye software. Each trap is identified byits transmitter number, and you have visible data on the date andtime of the last communication, the trap condition as well as the status of the signal and battery, and the trap location.

The RFC3300 transmitter is for use on applications where steam pressure is always above 0 psig. The second choice is theRFM3300 transmitter. It has a connection on the cover that can beconnected to a pressure or position switch. This switch connectionallows the unit to determine whether the steam is turned on to thesystem. If there is no steam on to the system (no pressure), the trap will not report any faults such as a cold trap. If steam is flowing(pressure) and the trap goes into a blow-thru or cold condition, analarm signal will be transmitted.

The RFM3000 would be used on modulated pressure applicationssuch as heat exchangers and air coils.

Mobile Receiver


TM-5

In locations where a dedicated personal computer is not practical, a mobile receiver can be used to monitor the SteamEye® transmitters.The unit can be powered by 110 volts AC or a battery. Battery powered,the unit can monitor for 12 hours on a single charge and be carried fromplace to place while monitoring the SteamEye transmitters. Pluggedinto 110 volts AC, the unit will recharge the battery (if a battery isused) and/or monitor the SteamEye transmitters indefinitely.

Data on up to 400 SteamEye transmitters can be loaded onto themobile receiver’s integral computer. When placed in an area to monitor SteamEye transmitters, the unit can show real-time steamtrap conditions. Using the software and cable provided, a snapshot of the steam trap condition data can be loaded onto a personalcomputer for viewing and reporting purposes. Instant notification of a trap failure can be achieved by wiring an alarm to an internalcontactor on the unit.

SteamEye and Building Automation Systems (BAS)If monitoring steam trap conditions through an existing BAS is desired, the SteamEye system can meet these needs. TheSteamEye receiver connected to a BAS interface controller collects information from SteamEye transmitters. The BAS interfacecontroller stores the information until queried by a BAS. The BASinterface controller then provides the information to the BAS in anopen protocol format (selected per application).

Get Your Share of Energy and Maintenance Savings. Do Your Part in Protecting the Environment.TrapAlert saves energy and maintenance dollars because it simplifies trap testing and makes it more efficient—more productive.It makes trap testing simple, accurate and quick—even for remoteor inaccessible traps. And that means frequent testing is now practi-cal because you can test more often at far less cost.

With TrapAlert, you can have an inside view of trap conditions. You’llknow when a trap needs attention. So you can use maintenancepeople to solve real problems, instead of spending their expensivetime checking traps that are working.

You Get Instant Results. Simple, accurate operation makes getting instant feedback from atrap test as easy as shining a flashlight.

With TrapAlert, you can know when a trap is in trouble—depending,of course, on how often you choose to test. Think of it as a trap witha built-in energy monitor. Knowing what’s going on inside is the onlyway to know what to do about it—and when.

TrapAlert Outsmarts Even the Most Isolated TrapTrapAlert provides a trap testing and monitoring system without the need to hard-wire multiple traps. Designed for services up to400 psi (28 bar) and temperatures to 450°F (232°C), TrapAlert isalso intrinsically safe for use in Class I, II or III, Division I, Groups A through G hazardous locations.

TA4200 TrapAlertModel TA4200 is ideal for traps isolated high above the floor, under equipment or otherwise out of reach. The TA4200 TrapAlertmakes testing a trap as easy as turning on a flashlight. The beam of a flashlight on TrapAlert’s photodetector energizes TrapAlert’s five-year lithium battery, which powers small indicator lights.Any flashlight will work close up, but for longer distances—even up to 50 feet (15 meters)—use a focusable high intensity model.

When a flashlight beam strikes the photodetector of the TA4200, the monitor responds instantly with one or more colored lights, indicating different trap conditions. A green light is a good or “go”condition. Yellow means a cold trap. And a red light signals loss of prime or blow-thru.

Flexible mounts on lights and photodetector permit angling themaway from building lights. They can be adjusted down for a high trap location or up for a low trap.
