The Cla-Val Model 50B-4KG1 Globe / 2050B-4KG1 Angle

Pressure Relief Valve is designed specifically to automati-

cally relieve excess pressure in fire protection pumping sys-

tems. Pilot controlled, it maintains constant system pres-

sure at the pump discharge within very close limits as

demands change.

At pump start, Cla-Val Relief Valve modulates to relieveexcess pump capacity, maintaining positive system pres-sure at the pump discharge.

When fire demand slows or ceases, Cla-Val Model50B-4KG1 opens, diverting entire pump output to dis-charge, allowing fire pump to be stopped without causingsurging in the lines.

(Please note that if the Model 50B-4KG1 is to be used ona continuous duty basis to maintain fire-system pressure,suitable back pressure must be provided on the valve toprevent cavitation damage. Consult the factory for details.)

DescriptionThe CIa-VaI Model 100-01 Hytrol Valve is a main valve forCIa-VaI Automatic Control Valves. It is a hydraulically operated,diaphragm-actuated, globe or angle pattern valve.

This valve consists of three major components; body, diaphragmassembly, and cover. The diaphragm assembly is the onlymoving part. The diaphragm assembly uses a diaphragm of nylonfabric bonded with synthetic rubber. A synthetic rubber disc,contained on three and one half sides by a disc retainer and discguide, forms a seal with the valve seat when pressure is appliedabove the diaphragm. The diaphragm assembly forms a sealedchamber in the upper portion of the valve, separating operatingpressure from line pressure.

Installation

1. Before valve is installed, pipe lines should be flushed of allchips, scale and foreign matter.2. It is recommended that either gate or block valves beinstalled on both ends of the 100-01 Hytrol Valve to facilitateisoIating the valve for preventive maintenance and repairs.3. Place the valve in the line with flow through the valve in thedirection indicated on the inlet nameplate. (See “Flow Direction”Section)4. Allow sufficient room around valve to make adjustments andfor disassembly.5. CIa-VaI 100-01 Hytrol Valves operate with maximum efficiencywhen mounted in horizontal piping with the cover UP, however,other positions are acceptable. Due to size and weight of thecover and internal components of 8 inch and larger valves,

installation with the cover UP is advisable. This makes internalparts readily accessible for periodic inspection.6. Caution must be taken in the installation of this valve to insurethat galvanic and/or electrolytic action does not take place. Theproper use of dielectric fittings and gaskets are required in allsystems using dissimilar metals.7. If a pilot control system is installed on the 100-01 Hytrol Valve,use care to prevent damage. If it is necessary to remove fittingsor components, be sure they are kept clean and replacedexactly as they were.8. After the valve is installed and the system is first pressurized,vent air from the cover chamber and pilot system tubing byloosening fittings at all high points.

Tight Closing OperationWhen pressure from the valve inlet (oran equivalent independent operatingpressure) is applied to the diaphragmchamber the valve closes drip-tight.

Full Open OperationWhen pressure in diaphragm chamberis relieved to a zone of lower pressure(usually atmosphere) the line pressure(5 psi Min.) at the valve inlet opens thevalve.

Modulating ActionValve modulates when diaphragm pres-sure is held at an intermediate pointbetween inlet and discharge pressure.With the use of a Cla-Val. "modulatingcontrol," which reacts to line pressurechanges, the pressure above thediaphragm is varied, allowing the valveto throttle and compensate for thechange.

Flow DirectionThe flow through the 100-01 Hytrol Valve can be in one of twodirections. When flow is “up-and-over the seat,” it is in “normal”flow and the valve will fail in the open position. When flow is “over-the seat-and down,” it is in “reverse” flow and the valve will fail inthe closed position. There are no permanent flow arrow markings.The valve must be installed according to nameplate data.

Normal Flow Reverse Flow

TroubleshootingThe following troubleshooting information deals strictly with theModel 100-01 Hytrol Valve. This assumes that all other compo-nents of the pilot control system have been checked out and arein proper working condition. (See appropriate sections inTechnical Manual for complete valve).

Three ChecksThe 100-01 Hytrol Valve has only one moving part (the diaphragmand disc assembly). So, there are only three major types of prob-lems to be considered.

First: Valve is stuck - that is, the diaphragm assembly is not freeto move through a full stroke either from open to close or viceversa.

Second: Valve is free to move and can’t close because of a wornout diaphragm.

Third: Valve leaks even though it is free to move and thediaphragm isn’t leaking.

Closed isolation valves in control system, or in main line.

Lack of cover chamber pressure.

Diaphragm damaged. (See Diaphragm Check.)

Diaphragm assembly inoperative.Corrosion or excessive scale build up on valve stem.(See Freedom of Movement Check)

Mechanical obstruction. Object lodged in valve.(See Freedom of Movement Check)

Worn disc. (See Tight Sealing Check)

Badly scored seat. (See Tight Sealing Check)

Closed upstream and/or downstream isolation valves in main line.

Insufficient line pressure.

Diaphragm assembly inoperative. Corrosion or excessivebuildup on valve stem. (See Freedom of Movement Check)

Diaphragm damaged. (For valves in "reverse flow" only)

After checking out probable causes and remedies, the following three checks can be used to diagnose the nature of theproblem before maintenance is started. They must be done in the order shown.

Open Isolation valves.

Check upstream pressure, pilot system, strainer, tubing, valves, or needlevalves for obstruction.

Replace diaphragm.

Clean and polish stem. Inspect and replace any damaged or badly erodedpart.

Remove obstruction.

Replace disc.

Replace seat.

Open isolation valves.

Check upstream pressure. (Minimum 5 psi flowing line pressure differential.)

Clean and polish stem. Inspect and replace anydamaged or badly eroded part.

Replace diaphragm.

Fails to Close

Fails to Open

CAUTION: Care should be taken when doing the troubleshooting checks onthe 100-01 Hytrol Valve. These checks do require the valve toopen fully. This will either allow a high flow rate through thevalve, or the downstream pressure will quickly increase to theinlet pressure. In some cases, this can be very harmful. Wherethis is the case, and there are no block valves in the system toprotect the downstream piping, it should be realized that thevalve cannot be serviced under pressure. Steps should betaken to remedy this situation before proceeding any further.

(cast into side of valve body)

SYMPTOM PROBABLE CAUSE REMEDY

Recommended Tools1. Three pressure gauges with ranges suitable to the instal-lation to be put at Hytrol inlet, outlet and cover connections.

2. Cla-Val Model X101 Valve Position Indicator. This pro-vides visual indication of valve position without disassemblyof valve.

3. Other items are: suitable hand tools such as screw-drivers, wrenches, etc. soft jawed (brass or aluminum) vise,400 grit wet or dry sandpaper and water for cleaning.

All trouble shooting is possible without removing the valve from theline or removing the cover. It is highly recommended to permanentlyinstall a Model X101 Valve Position Indicator and three gauges inunused Hytrol inlet, outlet and cover connections.

Diaphragm Check (#1 )1. Shut off pressure to the Hytrol Valve by slowly closing upstreamand downstream isolation valves. SEE CAUTION.

2. Disconnect or close all pilot control lines to the valve cover andleave only one fitting in highest point of cover open to atmosphere.

3.With the cover vented to atmosphere, slowly open upstreamisolation valve to allow some pressure into the Hytrol Valve body.Observe the open cover tapping for signs of continuous flow. It isnot necessary to fully open isolating valve. Volume in cover cham-ber capacity chart will be displaced as valve moves to open posi-tion. Allow sufficient time for diaphragm assembly to shift posi-tions. If there is no continuous flow, you can be quite certain thediaphragm is sound and the diaphragm assembly is tight. If thefluid appears to flow continuously this is a good reason to believethe diaphragm is either damaged or it is loose on the stem. Ineither case, this is sufficient cause to remove the valve cover andinvestigate the leakage. (See “Maintenance” Section for procedure.)

Freedom of Movement Check (#2)4. Determining the Hytrol Valve’s freedom of movement can bedone by one of two methods.

5. For most valves it can be done after completing DiaphragmCheck (Steps 1, 2, and 3). SEE CAUTION. At the end of step 3the valve should be fully open.

6. If the valve has a Cla-Val X101 Position Indicator, observe theindicator to see that the valve opens wide. Mark the point of max-imum opening.

7. Re-connect enough of the control system to permit the appli-cation of inlet pressure to the cover. Open pilot system cock sopressure flows from the inlet into the cover.

8. While pressure is building up in the cover, the valve shouldclose smoothly. There is a hesitation in every Hytrol Valve closure,which can be mistaken for a mechanical bind. The stem willappear to stop moving very briefly before going to the closed posi-tion. This slight pause is caused by the diaphragm flexing at aparticular point in the valve’s travel and is not caused by amechanical bind.

9. When closed, a mark should be made on the X101 Valve posi-tion indicator corresponding to the “closed” position. The distancebetween the two marks should be approximately the stem travelshown in chart.

10. If the stroke is different than that shown in stem travel chartthis is a good reason to believe something is mechanically restrict-ing the stroke of the valve at one end of its travel. If the flow doesnot stop through the valve when in the indicated “closed” position,the obstruction probably is between the disc and the seat. If theflow does stop, then the obstruction is more likely in the cover. Ineither case, the cover must be removed, and the obstruction locat-ed and removed. The stem should also be checked for scale build-up. (See “Maintenance, section for procedure.)

11. For valves 6” and smaller, the Hytrol Valve’s freedom of move-ment check can also be done after all pressure is removed fromthe valve. SEE CAUTION. After closing inlet and outlet isolationvalves and bleeding pressure from the valve, check that the coverchamber and the body are temporarily vented to atmosphere.Insert fabricated tool into threaded hole in top of valve stem, andlift the diaphragm assembly manually. Note any roughness. Thediaphragm assembly should move smoothly throughout entirevalve stroke. The tool is fabricated from rod that is threaded onone end to fit valve stem and has a “T” bar handle of some kindon the other end for easy gripping. (See chart in Step 4 of“Disassembly” Section.)

12. Place marks on this diaphragm assembly lifting tool when thevalve is closed and when manually positioned open. The distancebetween the two marks should be approximately the stem travelshown in stem travel chart. If the stroke is different than thatshown, there is a good reason to believe something is mechani-cally restricting the stroke of the valve. The cover must beremoved, and the obstruction located and removed. The stemshould also be checked for scale build-up. (See “Maintenance”Section for procedure.)

Tight Sealing Check (#3)13. Test for seat leakage after completing checks #1 & #2 (Steps1 to 12). SEE CAUTION. Close the isolation valve downstream ofthe Hytrol Valve. Apply inlet pressure to the cover of the valve, waituntil it closes. Install a pressure gauge between the two closedvalves using one of the two ports in the outlet side of the Hytrol.Watch the pressure gauge. If the pressure begins to climb, theneither the downstream isolation valve is permitting pressure tocreep back, or the Hytrol is allowing pressure to go through it.Usually the pressure at the Hytrol inlet will be higher than on theisolation valve discharge, so if the pressure goes up to the inletpressure, you can be sure the Hytrol is leaking. Install anothergauge downstream of isolating valve. If the pressure between thevalves only goes up to the pressure on the isolation valvedischarge, the Hytrol Valve is holding tight, and it was just the iso-lation valve leaking.

Maintenance

Preventative MaintenanceThe Cla-Val Co. Model 100-01 Hytrol Valve requires no lubrication orpacking and a minimum of maintenance. However, a periodic inspec-tion schedule should be established to determine how the operatingconditions of the system are affecting the valve. The effect of theseactions must be determined by inspection.

DisassemblyInspection or maintenance can be accomplished without removingthe valve from the line. Repair kits with new diaphragm and disc arerecommended to be on hand before work begins.

WARNING: Maintenance personnel can be injured and equipmentdamaged if disassembly is attempted with pressure in the valve. SEECAUTION.

1. Close upstream and downstream isolation valves and independ-ent operating pressure when used to shut off all pressure to thevalve.

2. Loosen tube fittings in the pilot system to remove pressure fromvalve body and cover chamber. After pressure has been releasedfrom the valve, use care to remove the controls and tubing. Note andsketch position of tubing and controls for re-assembly. The schemat-ic in front of the Technical Manual can be used as a guide whenreassembling pilot system.

3. Remove cover nuts and remove cover. If the valve has been inservice for any length of time, chances are the cover will have to beloosened by driving upward along the edge of the cover with a dullcold chisel.

On 6” and smaller valves block and tackle or a power hoist can beused to lift valve cover by inserting proper size eye bolt in place ofthe center cover plug. on 8” and larger valves there are 4 holes (5/8”— 11 size) where jacking screws and/or eye bolts may be insertedfor lifting purposes. Pull cover straight up to keep from damagingthe integral seat bearing and stem.

4. Remove the diaphragm and disc assembly from the valve body.With smaller valves this can be accomplished by hand by pullingstraight up on the stem so as not to damage the seat bearing.On large valves, an eye bolt of proper size can be installed in thestem and the diaphragm assembly can be then lifted with a block andtackle or power hoist. Take care not to damage the stem or bearings.The valve won't work if these are damaged.

5. The next item to remove is the stem nut. Examine the stemthreads above the nut for signs of mineral deposits or corrosion.If the threads are not clean, use a wire brush to remove as muchof the residue as possible. Attach a good fitting wrench to the nutand give it a sharp “rap” rather than a steady pull. Usuallyseveral blows are sufficient to loosen the nut for further removal.On the smaller valves, the entire diaphragm assembly can be heldby the stem in a vise equipped with soft brass jaws beforeremoving the stem nut.

The use of a pipe wrench or a vise without soft brass jaws scarsthe fine finish on the stem. No amount of careful dressing canrestore the stem to its original condition. Damage to the finish ofthe stem can cause the stem to bind in the bearings and the valvewill not open or close.

6. After the stem nut has been removed, the diaphragm assemblybreaks down into its component parts. Removal of the disc fromthe disc retainer can be a problem if the valve has been in serv-ice for a long time. Using two screwdrivers inserted along the out-side edge of the disc usually will accomplish its removal. Careshould be taken to preserve the spacer washers in water, partic-ularly if no new ones are available for re-assembly.

7. The only part left in the valve body is the seat which ordinarilydoes not require removal. Careful cleaning and polishing of insideand outside surfaces with 400 wet/dry sandpaper will usuallyrestore the seat’s sharp edge. If, however, it is badly worn andreplacement is necessary, it can be easily removed.

Seats in valve sizes 1 1/4” through 6” are threaded into the valvebody. They can be removed with accessory X109 Seat RemovingTool available from the factory. On 8” and larger valves, the seatis held in place by flat head machine screws. Use a tight-fitting,long shank screwdriver to prevent damage to seat screws. If uponremoval of the screws the seat cannot be lifted out, it will be nec-essary to use a piece of angle or channel iron with a hole drilledin the center. Place it across the body so a long stud can be insert-ed through the center hole in the seat and the hole in the angleiron. By tightening the nut a uniform upward force is exerted onthe seat for removal.

NOTE: Do not lift up on the end of the angle iron as this may forcethe integral bearing out of alignment, causing the stem to bind.

Lime Deposits

One of the easiest ways to remove lime deposits from the valvestem or other metal parts is to dip them in a 5-percent muriaticacid solution just long enough for the deposit to dissolve. Thiswill remove most of the common types of deposits. CAUTlON:USE EXTREME CARE WHEN HANDLING ACID. Rinse parts inwater before handling. If the deposit is not removed by acid, thena fine grit (400) wet or dry sandpaper can be used with water.

Reassembly

1. Reassembly is the reverse of the disassembly procedure. If anew disc has been installed, it may require a different number ofspacer washers to obtain the right amount of “grip” on the disc.When the diaphragm assembly has been tightened to a pointwhere the diaphragm cannot be twisted, the disc should be com-pressed very slightly by the disc guide. Excessive compressionshould be avoided. Use just enough spacer washers to hold thedisc firmly without noticeable compression.

2. MAKE SURE THE STEM NUT IS VERY TIGHT. Attach a goodfitting wrench to the nut and give it a sharp “rap” rather than asteady pull. Usually several blows are sufficient to tighten thestem nut for final tightening. Failure to do so could allow thediaphragm to pull loose and tear when subjected to pressure.

Test Procedure After Valve Assembly

There are a few simple tests which can be made in the field tomake sure the Hytrol Valve has been assembled properly. Dothese before installing pilot system and returning valve toservice. These are similar to the three troubleshooting tests.

1. Check the diaphragm assembly for freedom of movementafter all pressure is removed from the valve. SEE CAUTlON.Insert fabricated tool into threaded hole in top of valve stem, andlift the diaphragm assembly manually. Note any roughness,sticking or grabbing. The diaphragm assembly should movesmoothly throughout entire valve stroke. The tool is fabricatedfrom rod that is threaded on one end to fit valve stem (See chartin Step 4 of “Disassembly” section.) and has a “T” Bar handle ofsome kind on the other end for easy gripping.

Place marks on this diaphragm assembly lifting tool when thevalve is closed and when manually positioned open. The dis-tance between the two marks should be approximately the stemtravel shown in stem travel chart. (See “Freedom of MovementCheck” section.) If the stroke is different than that shown, thereis a good reason to believe something is mechanically restrictingthe stroke of the valve. The cover must be removed, the obstruc-tion located and removed. (See “Maintenance” Section forprocedure.)

Inspection of Parts

After the valve has been disassembled, each part should beexamined carefully for signs of wear, corrosion, or any otherabnormal condition. Usually, it is a good idea to replace the rub-ber parts (diaphragm and disc) unless they are free of signs ofwear. These are available in a repair kit. Any other parts whichappear doubtful should be replaced. WHEN ORDERlNGPARTS, BE SURE TO GIVE COMPLETE NAMEPLATE DATA,ITEM NUMBER AND DESCRlPTlON.

NOTE: If a new disc isn’t available, the existing disc can beturned over, exposing the unused surface for contact with theseat. The disc should be replaced as soon as practical.

3. Carefully install the diaphragm assembly by lowering the stemthrough the seat bearing. Take care not to damage the stem orbearing. Line up the diaphragm holes with the stud or bolt holeson the body. on larger valves with studs, it may be necessary tohold the diaphragm assembly up part way while putting thediaphragm over the studs.

4. Put spring in place and replace cover. Make sure diaphragmis Iying smooth under the cover.

5. Tighten cover nuts firmly using a cross-over pattern until allnuts are tight.

6. Test Hytrol Valve before re-installing pilot valve system.

Due to the weight of the diaphragm assembly this procedure isnot possible on valves 8” and larger. on these valves, the samedetermination can be made by carefully introducing a lowpressure-less than five psi) into the valve body with the covervented. SEE CAUTION. Looking in cover center hole see thediaphragm assembly lift easily without hesitation, and thensettle back easily when the pressure is removed.

2. To check the valve for drip-tight closure, a line should beconnected from the inlet to the cover, and pressure applied at theinlet of the valve. If properly assembled, the valve should holdtight with as low as ten PSI at the inlet. See “Tight SealingCheck” section.)

3. With the line connected from the inlet to the cover, apply fullworking pressure to the inlet. Check all around the cover for anyleaks. Re-tighten cover nuts if necessary to stop leaks past thediaphragm.

4. Remove pressure, then re-install the pilot system and tubingexactly as it was prior to removal. Bleed air from all highpoints.

5. Follow steps under “Start-Up and Adjustment” Section inTechnical Manual for returning complete valve back to service.

MODEL


Description 100-01 Hytrol ValveThe CIa-VaI Model 100-01 Hytrol Valve is a main valve forCIa-VaI Automatic Control Valves. It is a hydraulically operated,diaphragm-actuated, globe or angle pattern valve.

This valve consists of three major components; body, diaphragmassembly, and cover. The diaphragm assembly is the onlymoving part. The diaphragm assembly uses a diaphragm of nylonfabric bonded with synthetic rubber. A synthetic rubber disc,contained on three and one half sides by a disc retainer and discguide, forms a seal with the valve seat when pressure is appliedabove the diaphragm. The diaphragm assembly forms a sealedchamber in the upper portion of the valve, separating operatingpressure from line pressure.

Description 100-20 600 Series Hytrol ValveThe CIa-VaI Model 100-20 Hytrol Valve (600 Series main valve)have only one part -the body- that is different from standard 100Series Cla-Val main valve parts. The remaining parts of the 600series main valve are standard Cla-Val main valve parts.All service and maintenance information for the standard 100

Series main valves also apply to the 600 series main valves. The most important thing to remember when ordering mainvalve repair kits and replacement parts, except for the body, allother parts are going to be for a smaller size main valve. Cla-Val identifies main valve parts with the flange size of the stan-dard 100 Series main valve. Refer to the "Main Valve Sizes”chart below.

DESCRIPTIONThe CRL Pressure Relief Control is a direct acting, spring loaded,diaphragm type relief valve. It may be used as a self-contained valve oras a pilot control for a Cla-Val Main valve. It opens and closes withinvery close pressure limits.INSTALLATIONThe CRL Pressure Relief Control may be installed in any position. Thecontrol body (7) has one inlet and one outlet port with a side pipe plug(24) at each port. These plugs are used for control connections or gaugeapplications. The inlet in the power unit body (6) is the sensing line port.A flow arrow is marked on the body casting.OPERATIONThe CRL Pressure Relief Control is normally held closed by the force ofthe compression spring above the diaphragm; control pressure is appliedunder the diaphragm.

When the controlling pressure exceeds the spring setting, the disc is liftedoff its seat, permitting flow through the control.

When controlling pressure drops below spring setting, the spring returnsthe control to its normally closed position.

ADJUSTMENT PROCEDUREThe CRL Pressure Relief Control can be adjusted to provide a relief set-ting at any point within the range found on the nameplate.

Pressure adjustment is made by turning the adjustment screw (9) to varythe spring pressure on the diaphragm. Turning the adjustment screwclockwise increases the pressure required to open the valve.Counterclockwise decreases the pressure required to open the valve.

When pressure adjustments are complete the jam nut (10) should betightened and the protective cap (1) replaced. If there is a problem oftampering, lock wire holes have been provided in cap and cover. Wirethe cap to cover and secure with lead seal.

DISASSEMBLYThe CRL Pressure Relief Control does not need to be removed from theline for disassembly. Make sure that pressure shut down is accompaniedprior to disassembly. If the CRL is removed from the line for disassemblybe sure to use a soft jawed vise to hold body during work.

Refer to Parts List Drawing for Item Numbers.1. Remove cap (1), loosen jam nut (10) and turn adjusting

screw counterclockwise until spring tension is relieved.2. Remove the eight screws (4) holding the cover (3) and

powerunit body (6). Hold the cover and powerunit together and place on a suitable work surface. See NOTE under REASSEMBLY.

3. Remove the cover (3) from powerunit body (6). The spring (12) and two spring guides (11).

4. Remove nut (13) from stem (19) and slide off the belleville washer (14), the upper diaphragm washer (15) and the diaphragm (16).

5. Pull the stem (19) with the disc retainer assembly (21) through the bottom of powerunit. The lower diaphragm washer (17) will slide off of stem top.

6. Remove jam nut (23) and disc retainer assembly (21) from stem. Use soft jawed pliers or vise to hold stem. The polished surface of stem must not be scored or scratched.

7. The seat (22) need not be removed unless it is damaged. If removal is necessary use proper size socket wrench and turn counterclock-

wise.Note: Some models have an integral seat in the body (7).

INSPECTIONInspect all parts for damage, or evidence of cross threading. Checkdiaphragm and disc retainer assembly for tears, abrasions or other dam-age. Check all metal parts for damage, corrosion or excessive wear.REPAIR AND REPLACEMENTMinor nicks and scratches may be polished out using 400 grit wet or drysandpaper fine emery or crocus cloth. Replace all O-rings and any dam-aged parts.When ordering replacement parts, be sure to specify parts list item num-ber and all nameplate data.REASSEMBLYIn general, reassembly is the reverse of disassembly. However, the fol-lowing steps should be observed:

1. Lubricate the O-Ring (18) with a small amount of a good grade of waterproof grease, (Dow Corning 44 medium grade or equal). Use grease sparingly and install O-ring in powerunit body (6).

2. Install stem (19) in powerunit body (6). Use a rotating motion with minimum pressure to let stem pass through O-ring.

Do Not Cut O-Ring.

3. Install O-ring (5) at top of stem (19). Place lower diaphragm washer (17) on the stem with the serrated side up. Position diaphragm (16), upper diaphragm washer (15), with serration down, and belleville washer (14) with concave side down.

4. Position powerunit body (6) as shown on parts list drawing (top view).

5. Continue reassembly as outlined in disassembly steps 1 through 3.

Fire Protection Sprinkler Service Pressure Gauge

• UL listed and Factory Mutual approved

• Corrosion-resistant ABS case

• Heat-resistant ploycarbonate push-in window

• Patented PowerFlexTM movements with polyester segment

• True Zero indicationTM, a unique safety feature

Ashcroft fire protection sprinkler gauges are UnderwritersLaboratory listed and Factory Mutual approved for fire pro-tection sprinkler service. The case material on Type 1 005PXUL gauges is ABS. The 0-300 psi pressure range is usedon "wet" systems where water is available to the sprinklerheads. The 0-80 retard to 250 psi pressure range is usedon dry systems where the lines are filled with air pressureuntil system activation.

The patented PowerFlex movement with polyester segmentis designed to provide unequalled shock and vibrationresistance resulting in superior performance and extendedgauge life.

True Zero indication, a standard feature onthese gauges, reduces the potential risk ofinstalling a damaged gauge on your equipment.

N-Pressure Gauge (R-9/03)

The strainer is designed for use in conjunction with a Cla-ValMain Valve, but can be installed in any piping system wherethere is a moving fluid stream to keep it clean. When it is usedwith the Cla-Val Valve, it is threaded into the upstream body portprovided for it on the side of the valve. It projects through theside of the Main Valve into the flow stream. All liquid shunted tothe pilot control system and to the cover chamber of the MainValve passes through the X46 Flow Clean Strainer.

• Self Scrubbing Cleaning Action• Straight Type or Angle Type

The Cla-Val Model X46 Strainer is designed to prevent passage offoreign particles larger than .015". It is especially effective againstsuch contaminant as algae, mud, scale, wood pulp, moss, and rootfibers. There is a model for every Cla-Val. valve.

The X46 Flow Clean strainer operates on a velocity principle utiliz-ing the circular "air foil" section to make it self cleaning. Impingementof particles is on the "leading edge" only. The low pressure area onthe downstream side of the screen prevents foreign particles fromclogging the screen. There is also a scouring action, due to eddycurrents, which keeps most of the screen area clean.

Flow Clean StrainerX46

INSPECTIONInspect internal and external threads for damage or evidenceof cross-threading. Check inner and outer screens for clogging,embedded foreign particles, breaks, cracks, corrosion, fatigue,and other signs of damage.

CLEANINGAfter inspection, cleaning of the X46 can begin. Water service usually will producemineral or lime deposits on metal parts in contact with water. These deposits canbe cleaned by dipping X46 in a 5-percent muriatic acid solution just long enoughfor deposit to dissolve. This will remove most of the common types of deposits.Caution: use extreme care when handling acid. If the deposit is not removedby acid, then a fine grit (400) wet or dry sandpaper can be used with water.Rinse parts in water before handling. An appropriate solvent can clean parts usedin fueling service. Dry with compressed air or a clean, lint-free cloth. Protect from damage and dust until reassembled.

REPLACEMENTIf there is any sign of damage, or if there is the slightest doubt that the Model X46Flow Clean Strainer may not afford completely satisfactory operation, replace it.Use Inspection steps as a guide. Neither inner screen, outer screen, nor housing isfurnished as a replacement part. Replace Model X46 Flow Clean Strainer as a com-plete unit.

When ordering replacement Flow-Clean Strainers, it is important to determine pipesize of the tapped hole into which the strainer will be inserted (refer to column A orF), and the size of the external connection (refer to column B or G).

When Ordering,Please Specify:

• Catalog Number X46• Straight Type or Angle Type• Size Inserted Into and Size Connection• Materials

DISASSEMBLYDo not attempt to remove the screens from the strainer housing.
