Dry pilot sprinklers are to be minimum1/2 inch (15 mm) orifice listed or ap-proved automatic sprinklers, and re-mote manual pull stations, where re-quired, are to be Model MC-1 ManualControl Stations.

Graph B shows the “minimum pilot lineservice pressure” as a function of thewater supply pressure. The pressure inthe dry pilot actuation system must beautomatically maintained using one ofthe following maintenance devices, asappropriate.

• Model AMD-1 Air Maintenance De-vice (pressure reducing type), referto Technical Data Sheet TFP1221.

• Model AMD-2 Air Maintenance De-vice (compressor control type), referto Technical Data Sheet TFP1231.

• Model AMD-3 Nitrogen Mainte-nance Device (high pressure reduc-ing type), refer to Technical DataSheet TFP1241.

NOTESThe dewpoint of the pilot line air pres-sure must be maintained below thelowest ambient temperature to whichthe dry pilot actuation system will beexposed. Accumulation of water in thepilot line connection to the Actuator willlower the air pressure at which theActuator will open and possibly pre-vent proper operation. Also, introduc-tion of moisture into the pilot lines ex-posed to freezing temperatures cancreate an ice buildup which could pre-vent proper operation of the Actuator.

An air dryer must be installed wherethe moisture content of the air supplyis not properly controlled at less thanthe required value.

It is recommended that an AMD-3 Ni-trogen Maintenance Device be utilizedin dry pilot actuation system applica-tions where the dewpoint must bemaintained below -20°F/-29°C. SeeTechnical Data Sheet TFP1241.

It is recommended that internally gal-vanized pipe and cast iron fittings beused for dry pilot lines.

Supervision of the pressure in the drypilot actuation system and/or alarmthat separately indicates operation ofthe detection system is recommendedand may be required by the authorityhaving jurisdiction. A dual setting lowpressure alarm switch, such as thePotter Electric PS40-2A, is suitable forthe service. The recommended pres-sure settings are as follows:

• Low pressure alarm setting at ap-proximately 6 psi (0,4 bar) below theminimum pilot line service pressurerequirement shown in Graph B.

• Fire alarm setting at approximately15 psi (1,0 bar) below the minimumpilot line service pressure require-ment shown in Graph B.

The Pressure Relief Valve (Ref. Item 4- Fig. 5 ) is factory set to relieve at apressure of approximately 45 psi (3,1bar); however, it may be field adjustedto a lower pressure if required.

ElectricActuation(Basic Trim plus Alarm & TestTrim plus Electric Actuation Trim)Electric Actuation is required for elec-tric operation of the Model DV-2 Del-uge Valve by a detection system con-sisting of electrical devices such asheat sensitive thermostats, smoke de-tectors, and/or electric manual pull sta-tions. Information on the various typesof separately ordered Solenoid Valvesthat may be used with the Electric Ac-tuation Trim is given in Technical DataSheet TFP2180.

NOTEApproval by Factory Mutual is contin-gent on the use of an FM Approved24VDC Solenoid Valve. FM only ap-proves solenoid valves for use in non-hazardous locations.

The Electric Actuation Trim is only tobe used in conjunction with an electricdeluge valve releasing panel (auto-matic control unit) that is listed or ap-proved (as appropriate) for fire protec-tion system releasing service. Inaddition, the deluge valve releasingpanel is only to be operated by listedor approved (as appropriate) fire de-tectors.

Operation of an electrical device suchas heat sensitive thermostat, smokedetector, or electric manual pull stationsignals the deluge valve releasingpanel to energize the Solenoid Valve.In turn, the energized Solenoid Valveopens resulting in a rapid pressuredrop in the Upper Chamber of theModel DV-2 Deluge Valve, and theforce differential holding the ModelDV-2 Deluge Valve in the set positionis eliminated.

NOTEConsult with the Authority Having Ju-risdiction regarding installation criteriapertaining to electric actuation cir-cuitry.

OperatingPrinciplesThe Model DV-2 Deluge Valve is a dif-ferential valve that depends uponwater pressure in the Upper Chamberto hold the Center Valve Assemblyclosed against the water supply pres-sure. The nominal trip ratio is 2.5 to 1,i.e., the Model DV-2 Deluge Valve op-erates (opens) when the pressure inthe Upper Chamber is reduced to ap-proximately 40 percent of the watersupply pressure.

When the Model DV-2 Deluge Valve isset for service, the Upper Chamber ispressurized through the trim connec-tions from the inlet side of the system’smain control valve (Fig. 2). Opening ofan actuation device, for example thesolenoid valve in the Electric ActuationTrim (Fig. 6), releases water from theUpper Chamber faster than it can bereplenished through the 1/8" (3,2 mm)Restriction in the Upper Chamber Sup-ply Connection (Item 8 - Fig. 2). Thisresults in a rapid pressure drop in theUpper Chamber and the force differen-tial holding the Center Valve Assemblydown in the set position is eliminated.The water supply pressure then forcesthe Center Valve Assembly open, per-mitting water to flow into the systempiping, as well as through the Alarm &Test Trim (Fig. 4) to actuate systemalarms.

InstallationNOTES

Proper operation of the Model DV-2Deluge Valve depends upon its trimbeing installed in accordance with theinstructions given in this TechnicalData Sheet. Failure to follow the ap-propriate trim diagram may preventthe Model DV-2 Deluge Valve fromfunctioning properly, as well as voidlistings, approvals, and the manufac-turer’s warranties.

The Model DV-2 Deluge Valve must beinstalled in a readily visible and acces-sible location.

The Model DV-2 Deluge Valve, asso-ciated trim, and wet pilot lines must bemaintained at a minimum temperatureof 40°F/4°C.

Heat tracing of the Model DV-2 DelugeValve or its associated trim is not per-mitted. Heat tracing can result in theformation of hardened mineral depos-its which are capable of preventingproper operation.

The Model DV-2 Deluge Valve is to beinstalled in accordance with the follow-ing criteria:

Step 1. All nipples, fittings, and de-vices must be clean and free of scaleand burrs before installation. Use pipethread sealant sparingly on male pipethreads only.

NOTEIt is recommended that internally gal-vanized pipe and cast iron fittings beused for wet or dry pilot lines.

Step 2. Refer to Figure 3 for installa-tion of either the 2 or 2-1/2 inch Dis-charge Trim, as applicable. If a 1-1/2inch discharge is required, the 1-1/2inch outlet connection on the righthand side of the Model DV-2 DelugeValve must be plugged.

Step 3. The Model DV-2 Deluge Valvemust be trimmed in accordance withFigures 2 and 4, as well as Figures 5and 6 as applicable. The Basic Trimhas been designed to facilitate use ofa gate valve having an end-to-end di-mension of 3-7/8 inches. If anothertype of main control valve is to beused, the connection to the UpperChamber Supply Control Valve may bemodified accordingly.

Step 4. Care must be taken to makesure that check valves, strainers,globe valves, etc. are installed with theflow arrows in the proper direction.

Step 5. Drain tubing to the drip funnelmust be installed with smooth bendsthat will not restrict flow.

Step 6. The main drain and flow testdrain may be interconnected to thedrip funnel drain provided a checkvalve is located at least 12 inches (300mm) below the drip funnel.

Step 7. Suitable provision must bemade for disposal of drain water.Drainage water must be directed suchthat it will not cause accidental dam-age to property or danger to persons.

Step 8. An Inspector’s Test Connec-tion, as described in the Wet Pilot Ac-tuation or Dry Pilot Actuation section,must be provided for Wet or Dry PilotActuation.

Step 9. An Air Maintenance Device, asdescribed in the Dry Pilot Actuationsection, must be provided for Dry PilotActuation.

Step 10. A desiccant dryer, whenspecified for Dry Pilot Actuation, is tobe installed between a drip leg and theAir Maintenance Device.

Step 11. The Low Pressure AlarmSwitch for Dry Pilot Actuation is to beadjusted as follows:


• Fire alarm setting at approximately

15 psi (1,0 bar) below the minimumpilot line service pressure require-ment shown in Graph B.

Step 12. Unused pressure alarmswitch connections must be plugged.

Step 13. The Pressure Relief Valveprovided with the Dry Pilot ActuationTrim is factory set to relieve at a pres-sure of approximately 45 psi (3,1 bar),which can typically be used for a maxi-mum normal dry pilot actuation systempressure of 40 psi (2,8 bar). The Pres-sure Relief Valve may be reset; how-ever, it must be be reset to relieve at apressure that is in accordance with therequirements of the authority havingjurisdiction.

To reset the Pressure Relief Valve, firstloosen the jam nut and then adjust thecap accordingly — clockwise for ahigher pressure setting or counter-clockwise for a lower pressure setting.After verifying the desired pressuresetting, tighten the jam nut.

Step 14. Conduit and electrical con-nections are to be made in accordancewith the requirements of the authorityhaving jurisdiction and/or the NationalElectric Code.

SettingProcedureSteps 1 through 12 are to be per-formed when initially setting the ModelDV-2 Deluge Valve; after an opera-tional test of the fire sprinkler system;or, after system operation due to a fire.

Step 1. Close the Upper ChamberSupply Control Valve (Fig. 2).

Step 2. Close the Main Control Valve.If the system is equipped with Dry PilotActuation, close the Air Supply ControlValve (Fig. 5).

Step 3. Open the Main Drain Valve(Fig. 2), Flow Test Valve (Fig. 2), andall auxiliary drains in the system. Closethe Main Drain Valve and auxiliarydrain valves after water ceases to dis-charge. Leave the Flow Test Valveopen.

Step 4. Depress the plunger of theAutomatic Drain Valve (Fig. 2) to verifythat it is open and that the Model DV-2Deluge Valve is completely drained.

Step 5. Clean the Strainer (Fig. 2) inthe Upper Chamber Supply Connec-tion by removing the clean-out plugand strainer basket. The Strainer maybe flushed by momentarily opening theUpper Chamber Supply Control Valve.

Step 6. Open the Alarm Control Valve(Fig. 4) if it was closed to silence localalarms.

It is recommended that the Alarm Con-trol Valve be wire sealed in the openposition with a No. 16 twisted wire, theends of which are secured by a leadseal. The wire seal should be loopedthrough the hole in the handle andtightly twisted around the pipe nippleadjacent to the handle.

Step 7. Reset the actuation system.

Manual Actuation — Reset the ManualControl Station (Fig. 2); however, donot close the hinged cover at this time.

Wet Pilot Actuation — Replace oper-ated pilot sprinklers and/or reset themanual control stations.

Dry Pilot Actuation — Replace oper-ated pilot sprinklers and/or reset themanual control stations. Re-establishdry pilot pneumatic pressure.

Electric Actuation — Reset the electricdetection system in accordance withthe manufacturer’s instructions to de-energize the solenoid valve.

NOTEIn order to prevent the possibility of asubsequent operation of an over-heated solder type sprinkler, any sol-

der type sprinklers that were possiblyexposed to a temperature greater thantheir maximum rated ambient must bereplaced.

Step 8. Remove the Cover from theModel DV-2 Deluge Valve, and thenremove the Center Valve Assembly.Thoroughly clean and inspect the Cen-ter Valve Assembly for wear or dam-age, as well as all interior surfaces ofthe Valve Body and Cover. Specialconsideration should be given to thecondition of the Diaphragm and Fac-ing. The Diaphragm and/or Facingshould be replaced if there are anysign of deterioration due to age orchemicals in the water. If the watersupply contains chemicals which tendto attack an EPDM type rubber, thenthe frequency of the Diaphragm andfacing inspection should be increasedto at least annually.

Worn or damaged parts must be re-placed and the Model DV-2 DelugeValve must be reassembled in accord-ance with Figure 1. The Cap Screwssecuring the Cover should be uni-formly tightened using a cross-drawsequence.

Step 9. Open the Upper ChamberSupply Control Valve (Fig. 2) and allowtime for full pressure to build up in theUpper Chamber.

Step 10. Operate (open) the ManualControl Station (Fig. 2) to vent trappedair from the Upper Chamber. If neces-sary, first open the hinged cover, andthen fully pull down on the operatinglever. SLOWLY close the operatinglever, by pushing it up after aeratedwater ceases to discharge from theManual Control Station drain tubing.Close the hinged cover and insert anew break rod in the small holethrough the top of the enclosing box.

If wet pilot actuation is being used,crack open the Inspector’s Test Con-nection and any other vent valves, torelieve trapped air. After the dischargeof air has stopped, close the ventvalves and the Inspector’s Test Con-nection.

Step 11. Inspect drain connectionsfrom the Manual Control Station, Sole-noid Valve, Dry Pilot Actuator, andAlarm Devices, as applicable. Anyleaks must be corrected before pro-ceeding to the next step.

Step 12. Slowly open the Main ControlValve. Close the Flow Test Valve (Fig.2) as soon as water discharges fromthe Flow Test Valve. Observe the Auto-matic Drain Valve (Fig. 2) for leaks. Ifthere are leaks, determine/correct thecause of the leakage problem. If thereare no leaks, the Model DV-2 DelugeValve is ready to be placed in service

and the Main Control Valve must thenbe fully opened.

NOTEAfter setting a fire protection system,notify the proper authorities and ad-vise those responsible for monitoringproprietary and/or central stationalarms.

Care andMaintenanceThe following procedures and inspec-tions must be performed as indicated,in addition to any specific require-ments of the NFPA, and any impair-ment must be immediately corrected.

The owner is responsible for the in-spection, testing, and maintenance oftheir fire protection system and de-vices in compliance with this docu-ment, as well as with the applicablestandards of any authorities having ju-risdiction. The installing contractor orproduct manufacture should be con-tacted relative to any questions.

It is also recommended that automaticspr inkler systems be inspected,tested, and maintained by a qualifiedInspection Service.

NOTESSome of the procedures outlined inthis section will result in operation ofthe associated alarms. Consequently,notification must be given to the ownerand the fire department, central sta-tion, or other signal station to which thealarms are connected.

Before closing a fire protection systemmain control valve for maintenancework on the fire protection system thatit controls, permission to shut down theaffected fire protection systems mustfirst be obtained from the properauthorities and all personnel who maybe affected by this decision must benotified.

Drop In Water Supply Pressure Be-low Normal Range

NOTEIf the water supply pressure is signifi-cantly reduced below the normally ex-pected static pressure range (as couldoccur in the case of a water main breakor repair), and there is a subsequentdrop in the upper chamber water pres-sure below its normal range (due, forexample, to a leak in a piping connec-tion to or from the upper chamber or, aleak in the upper chamber check valvecaused by dirt or debris in the checkvalve seal area), a deluge valve suchas the Model DV-2 could inadvertently

trip if its water supply pressure isquickly restored.

A drop in the water supply pressurebelow its normal range (as in the caseof an interrupted water supply condi-tion) constitutes an emergency impair-ment as defined by NFPA 25. Shouldthis condition occur, immediatelyclose the main control valve and util-ize the following procedure to reset thesystem:

Step 1. Prior to the water supply pres-sure being restored to the closed maincontrol valve, note the pressure indi-cated by the upper chamber pressuregauge and, whether the pressure iswithin the normally expected range.

Step 2. If the upper chamber pressureis below the normal range, check forand correct any source of leakagefrom the upper chamber, prior to reset-ting the system.

Step 3. After the water supply pres-sure is restored to the main controlvalve, reset the Model DV-2 DelugeValve in accordance with the ValveSetting Procedure section.

NOTEFor fire protection systems subject toan emergency impairment caused byan interrupted water supply condition,it is recommended that considerationbe given to installing a low water sup-ply pressure switch, with the appropri-ate alarm/indications, to monitor thewater supply pressure

Annual Operation Test ProcedureProper operation of the DV-2 Valve(i.e., opening of the DV-2 Valve as dur-ing a fire condition) must be verified atleast once a year as follows:

Step 1. If water must be preventedfrom flowing beyond the riser, performthe following steps.

• Close the Main Control Valve.

• Open the Flow Test Valve.

• Open the Main Control Valve oneturn beyond the position at whichwater just begins to flow from theFlow Test Valve.

• Close the Flow Test Valve.

Step 2. Determine the type of actua-tion/detection system, and operate theDV-2 Valve accordingly.

NOTEBe prepared to quickly perform Steps3, 4, and 5, if water must be preventedfrom flowing beyond the riser.

• Wet Pilot Actuation — Open theInspector’s Test Connection.

• Dry Pilot Actuation — Open theInspector’s Test Connection.

• Electric Actuation — Test the del-uge releasing panel (automatic con-trol unit) in accordance with themanufacturer’s instructions to ener-gize the solenoid valve.

Step 3. Verify that the DV-2 Valve hastripped, as indicated by the flow ofwater into the system.

Step 4. Close the Upper ChamberSupply Control Valve.

Step 5. Close the system’s Main Con-trol Valve.

Step 6. Reset the DV-2 Valve in ac-cordance with the Valve Setting Proce-dure.

Quarterly Waterflow Alarm TestProcedureTesting of the the system waterflowalarms must be performed quarterly.To test the waterflow alarm, close theAlarm Control Valve and then open theAlarm Test Valve, allowing a flow ofwater to the Pressure Alarm Switchand/or Water Motor Alarm. Upon satis-factory completion of the test, closethe Alarm Test Valve and then open theAlarm Control Valve.

It is recommended that the Alarm Con-trol Valve be wire sealed in the openposition with a No. 16 twisted wire, theends of which are secured by a leadseal. The wire seal should be loopedthrough the hole in the handle andtightly twisted around the pipe nippleadjacent to the handle.

Quarterly Solenoid Valve TestProcedure For Electric ActuationProper operation of the Solenoid Valvefor electric actuation must be verifiedat least quarterly as follows:

Step 1. Close the Main Control Valve.

Step 2. Open the Flow Test Valve.

Step 3. Test the automatic control unit(deluge releasing panel) in accord-ance with the manufacturer’s instruc-tions to energize the solenoid valve.

Step 4. Verify that the flow of waterfrom the Solenoid Valve drain connec-tion increases to a full flow.

Step 5. Verify that the Upper Chamberpressure has decreased to below 25%of the water supply pressure.

Step 6. Reset the electric detectionsystem in accordance with the manu-facturer’s instructions to de-energizethe solenoid valve. Check the SolenoidValve drain for leaks. Any leaks mustbe corrected before proceeding to thenext step.

Step 7. Slowly open the Main Control

Valve. Close the Flow Test Valve assoon as water discharges from thedrain connection. Observe the Auto-matic Drain Valve for leaks. If there areleaks, determine/correct the cause ofthe leakage problem. If there are noleaks, the DV-2 Valve is ready to beplaced in service and the Main ControlValve must then be fully opened.
