22 TYCO DRY VALVESGeneral Description The Tyco ®Model DPV-1 Dry Pipe Valves are differential valves used to automatically control the flow of water into dry pipe fire protection sprinkler systems upon operation of one or more automatic sprinklers. The DPV-1 also provides for actuation of fire alarms upon system operation. The Model DPV-1 features are as follows: •External reset. •250 psi (17,2 bar) pressure rating. •Unique offset single clapper design enabling a simple compact valve to minimize installation labor. •Ductile iron construction to ensure a lightweight valve to minimize ship- ping cost. •A variety of inlet and outlet connec- tions. •Compact, semi-preassembled or fullyassembled,andeasytooperate valve trim. •Simple reset procedure through the elimination of priming water. Dry pipe sprinkler systems are used in unheated warehouses, parking ga- rages, store windows, attic spaces, loading docks, and other areas ex- posedtofreezingtemperatures,where water filled pipe cannot be utilized. When set for service, the dry pipe sprinklersystem is pressurizedwithair (or nitrogen). The loss of pressure through an operated automatic sprin- kler in response to heat from a fire permits the DPV-1 Dry Pipe Valve to open and allow a flow of water into the sprinkler system piping. Table B es- tablishes the minimum required sys- tem air pressure that includes a safety factor to help prevent false operations that might occur due to water supply fluctuations. WARNING The Model DPV-1 Dry Pipe Valves de- scribed herein must be installed and maintained in compliance with this document, as well as with the applica- ble standards of the National Fire Pro- tection Association, in addition to the standards of any other authorities hav- ing jurisdiction.Failure to do so may impair the performance of these de- vices. The owner is responsible for maintain- ing their fire protection system and de- vices in proper operating condition. The installing contractor or manufac- turer should be contacted with any questions.

DESCRIPTION P/N REPLACEMENT PARTS Technical Data Approvals: UL and C-UL Listed. FM Approved. NYC under MEA 172-02-E (4 and 6 inch). DryPipeValve: The Model DPV-1 Dry Pipe Valves are for vertical installations (flow going up), and they are rated for use at a maximum service pressure of 250 psi (17,2 bar). The Valve dimensions are shown in Figure 7. Flanged connections are available drilled per ANSI, ISO, AS, and JIS specifications (Ref. Table A). The grooved outlet connections, as appli- cable, are cut in accordance with standard groove specifications for steel pipe. They are suitable for use with grooved end pipe couplings that are listed or approved for fire protec- tion system service. Available combi- nations of inlet and outlet connections are detailed in the Ordering Procedure section. Threaded port connections of valves having flanges drilled to ANSI, AS, or JIS specifications are NPT threaded per ANSI Standard B1.20.1. Threaded port connections of valves having flanges drilled to ISO are available either threaded per ISO 7/1 or NPT threaded per ANSI Standard B1.20.1. Valves with NPT threaded ports will readily accept the trim arrangements detailed in Figures 4, 5, and 6. Components of the DPV-1 Valves are shown in Figure 1. The Body and Handhole Cover are ductile iron. The Handhole Cover Gasket is neoprene, and the Clapper Facing is EPDM. The Air/Water Seat Ring is brass, the Clap- per is bronze or aluminum bronze, and both the Clapper Retaining Plate and Latch are bronze. The Hinge Pin is aluminum bronze, and the fasteners for the Handhole Cover are carbon steel. Valve Trim: Installation dimensions are given in Figure 7, and the Valve Trim is illus- trated in Figures 4, 5, and 6. The Valve Trim forms a part of the laboratory listings and approval of the DPV-1 Valve and is necessary for the proper operation of the DPV-1 Valve. Each package of trim includes the following items: •Water Supply Pressure Gauge •System Air Pressure Gauge •Air Supply Connections •Main Drain Valve •Low Body Drain Valve •Alarm Test Valve •Automatic Drain Valve •Drip Funnel •Connections For Optional Quick Opening Device (Accelerator) NOTE When the system pressure is greater than 175 psi (12,1 bar), provision is to be made to replace the standard order 300 psi (20,7 bar) Water Pressure gauge with a separately ordered 600 psi (41,4 bar) Water Pressure Gauge. Air Supply: Table B shows the system air pressure requirementsasafunctionofthewater supply pressure. The air (or nitrogen) pressure in the sprinkler system is rec- ommended to be automatically main- tained by using one of the following pressure maintenance devices, as ap- propriate: •Model AMD-1 Air Maintenance De- vice (pressure reducing type). •Model AMD-2 Air Maintenance De- vice (compressor control type). •Model AMD-3 Nitrogen Mainte- nance Device (high pressure reduc- ing type). The Pressure Relief Valve provided with the valve trim is factory set to relieve at a pressure of approxi- mately 45 psi (3,1 bar). If the normal system air pressure is less than or exceeds 40 psi (2,8 bar), then the pressure Relief Valve must be reset to relieve at a pressure that is in accord- ance with the Authority Having Juris- diction. Quick Opening Device: As an option, the Model DPV-1 Dry Pipe Valve may be equipped with the Model QRS Electronic Dry Pipe Valve Accelerator (4 and 6 inch sizes) as detailed in Technical Data Sheet TFP1100 or the Model ACC-1 Me- chanical Dry Pipe Valve Accelerator (2-1/2, 3, 4, and 6 inch sizes) as de- tailed in Technical Data Sheet TFP1112. TheQRSortheACC-1isusedtore- duce the time to valve actuation fol- lowing the operation of one or more automatic sprinklers. In some cases the use of a quick opening device such astheQRSortheACC-1maybere- quired to meet the requirements of the National Fire Protection Association to meet water delivery times.

The differential nature of the DPV-1 is based on the area difference between the air seat and the water seat in combination with the ratio of the radial difference from the Hinge Pin to the center of the Water Seat and the Hinge Pin to the center of the Air Seat. The difference is such that 1 psi (0,07 bar) of system air pressure can hold approximately 5.5 psi (0,38 bar) of water supply pres- sure. Table B establishes the minimum re- quired system air pressure that in- cludes a safety factor to help prevent false operations that occur due to water supply fluctuations. The Intermediate Chamber of the DPV-1isformedbytheareabetween the Air Seat and Water Seat as shown in Figure 3B. The Intermediate Cham- ber normally remains at atmospheric pressure through the Alarm Port con- nection and the valve trim to the nor- mally open Automatic Drain Valve (Fig. 4, 5, or 6). Having the Intermedi- ate Chamber, Figure 3B, open to at- mosphere is critical to the DPV-1 Valve remaining set, otherwise the full resulting pressure of the system air pressure on top of the Clapper Assem- bly cannot be realized. For example and assuming a water supply pressure of 100 psi (6,9 bar), if the system air pressure is 25 psi (1,7 bar) and there was 15 psi (1,0 bar) pressure trapped in the Intermediate Chamber, the resulting pressure across the top of the Clapper would only be 10 psi (0,7 bar). This pressure would be insufficient to hold the Clap- per Assembly closed against a water supply pressure of 100 psi (6,9 bar). It is for this reason thatthe plunger ofthe Automatic Drain Valve must be de- pressed during several of the resetting steps, as well as during inspections, making certain that the Automatic Drain Valve is open. When one or more automatic sprin- klers operate in response to a fire, air pressure within the system piping is relieved through the open sprinklers. When the air pressure is sufficiently reduced, the water pressure over- comes the differential holding the Clapper Assembly closed and the Clapper Assembly swings clear of the water seat, as shown in Figure 3C, This action permits water flow into the system piping and subsequently to be discharged from any open sprinklers. Also, with the Clapper Assembly open, the intermediate chamber is pressur- ized and water flows through the alarm port (Ref. Figure 3B) at the rear of the DPV-1 Valve to actuate system water flow alarms. The flow from the alarm port is also sufficient to close the oth- erwise normally open Automatic Drain Valve in the valve trim. After a valve actuation and upon sub- sequent closing of a system main con- trol valve to stop water flow, the Clap- per Assembly will latch open as shown in Figure 3D. Latching open of the DPV-1 will permit complete draining of the system (including any loose scale) through the main drain port. During the valve resetting procedure and after the system is completely drained, the external reset knob can be easily depressed to externally un- latch the Clapper Assembly as shown in Figure 3E. As such, the Clapper Assembly is returned to its normal set position to facilitate setting of the dry pipe sprinkler system, without having to remove the Handhole Cover.

Failure to follow the ap- propriate trim diagram may prevent the DPV-1 Valve from functioning properly, as well as void listings, ap- provals, and the manufacturer’s war- ranties. Failure to latch open the Clapper As- sembly prior to a system hydrostatic test may result in damage to the Clap- per Assembly. The DPV-1 Valve must be installed in a readily visible and accessible loca- tion. The DPV-1 Valve and associated trim mustbe maintained at a minimum tem- perature of 40°F/4°C. Heat tracing of the DPV-1 Valve or its associated trim is not permitted. Heat tracing can result in the formation of hardened mineral deposits that areca- pable of preventing proper operation. The Model DPV-1 Dry Pipe Valve is to be installed in accordance with the fol- lowing criteria: Step 1.All nipples, fittings, and de- vices must be clean and free of scale and burrs before installation. Use pipe thread sealant sparingly on male pipe threads only. Step 2.The DPV-1 Valve must be trimmed in accordance with Figures 4, 5, or 6, as applicable. If the DPV-1 is to be equipped with a Dry Pipe Valve Accelerator, refer to the Technical Data Sheet TFP1100 for the Model QRS Electronic Dry Pipe Valve Accel- erator or TFP1112 for the Model ACC- 1 Mechanical Dry Pipe Valve Accel- erator. Step 3.Care must be taken to make sure that check valves, strainers, globe valves, etc. are installed with the flow arrows in the proper direction. Step 4.Drain tubing to the drip funnel must be installed with smooth bends that will not restrict flow. Step 5.The main drain and drip funnel drain may be interconnected provided a check valve is located at least 12 inches(300mm) below thedripfunnel. The Low Body Drain Valve (Fig. 4, 5, or 6) may be piped so as to discharge into the Drip Funnel or to a separate drain. Step 6.Suitable provision must be made for disposal of drain water. Drainage water must be directed such that it will not cause accidental dam- age to property or danger to persons. Step 7.Unused pressure alarm switch and/or water motor alarm connections must be plugged. Step 8.ThePressureReliefValvepro- vided with the Valve Trim is factory set to relieve at a pressure of approxi- mately 45 psi (3,1 bar), which can typi- cally be used for a maximum normal system air pressure of 40 psi (2,8 bar). The Pressure Relief Valve may be re- set to a lower or higher pressure; how- ever, it must be be reset to relieve at a pressure which is in accordance with the requirements of the Authority Hav- ing Jurisdiction. To reset the Pressure Relief Valve, first loosen the jam nut and then adjust the cap accordingly — clockwise for a higher pressure setting or counter- clockwise for a lower pressure setting. After verifying the desired pressure setting, tighten the jam nut. Step 9.Installation of an Air Mainte- nance Device, as described in the Technical Data Section, is recom- mended. Step 10.An Inspector’s Test Connec- tion as required By NFPA 13 must be provided on the system piping at the most remote location from the Model DPV-1 Valve. Step 11.Conduit and electrical con- nections aretobemade inaccordance with the requirements of the authority having jurisdiction and/or the National Electric Code. Step 12.Before a system hydrostatic test is performed in accordance with NFPA 13 system acceptance test re- quirements, the Clapper Assembly is to be manually latched open (Ref. Fig. 3D); the Automatic Drain Valve (Fig. 4, 5, or 6) is to be temporarily replaced with a 1/2 inch NPT plug, the 3/32 inch Vent Fitting (Item 13, Fig. 4; Item 15, Fig. 5; or Item 15, Fig. 6) is to be temporarily replaced with a 1/4 inch NPT plug, and the Handhole Cover Bolts areto betightenedusingacross- draw sequence. Valve Setting Procedure Steps 1 through 11 are to be per- formed when initially setting the Model DPV-1 Dry Pipe Valve; after an opera- tional test of the fire protection system; or, after system operation due to a fire. NOTES If the DPV-1 is equipped with a Dry Pipe Valve Accelerator, refer to its re- setting instructions before resetting the DPV-1. Refer to TFP1100 for the QRS or TFP1112 for the ACC-1. Based ontheinstructions provided,re- set the Accelerator at the appropriate time during the resetting of the DPV-1. Step 1.Close the Main Control Valve, and close the Air Supply Control Valve (Fig.4,5,or6).IftheDPV-1is equipped with a Dry Pipe Valve Accel- erator, remove the Dry Pipe Valve Ac- celerator from service in accordance with its Technical Data Sheet (Refer to TFP1100 for the QRS or TFP1112 for the ACC-1). Step 2.Open the Main Drain Valve (Fig. 4, 5, or 6) and all auxiliary drains in the system. Close the auxiliary drain valves after water ceases to dis- charge. Leave the Main Drain Valve open. Step 3.Depress the plunger of the Automatic Drain Valve (Fig. 4, 5, or 6) to verify that it is open and that the DPV-1 Valve is completely drained. Step 4.Open the Optional Alarm Con- trol Valve (Fig. 4, 5, or 6), as applica- ble, if it was closed to silence local alarms. Step 5.As necessary, replace all sprinklers that have operated. Re- placement sprinklers must be of the same type and temperature rating as those which have operated. NOTE In order to prevent the possibility of a subsequent operation of an over- heated solder type sprinkler, any sol- der type sprinklers which were possi- bly exposed to a temperature greater than their maximum rated ambient must be replaced. Step 6.Push down on the Reset Knob (Fig. 3E) to allow the Clapper Assem- bly to reseat. Step 7.Pressurize the system with air (or nitrogen) to 10 psi (0,7 bar), and then individually open all auxiliary drain valves in the system piping to drain any remaining water in trapped sections. Close each drain valve as soon as water ceases to discharge. Page 16 of 20 TFP1020 Also partially open the Low Body Drain Valve (Fig. 4, 5, or 6) to assure that the riser is completely drained. Close the Low Body Drain Valve as soon as water ceases to discharge. Step 8.Refer to Table B and then restore the system to the normal sys- tem air pressure as necessary to hold the DPV-1 Valve closed. Step 9.Depress the plunger on the Automatic Drain Valve to make sure it is open and that there is no air dis- charging. The absence of air discharging from the Automatic Drain Valve is an indica- tion of a properly set air seat within the DPV-1 Valve.Ifairisdischarging,refer to the Care and Maintenance section under Automatic Drain Valve Inspec- tion to determine/correct the cause of the leakage problem. Step 10.Partially open the Main Con- trol Valve. Slowly close the Main Drain Valve as soon as water discharges from the drain connection. Depress the plunger on the Automatic DrainValvetomakesurethatitisopen and that there is no water discharging. The absence of water discharging from the Automatic Drain Valve is an indication of a properly set water seat within the DPV-1 Valve. If water is dis- charging, refer to the Care and Main- tenance section under the Automatic Drain Valve Inspection to deter- mine/correct the cause of the leakage problem. If there are no leaks, the DPV-1 Valve is ready tobeplaced inservice and the Main Control Valve must then be fully opened. NOTE After setting a fire protection system, notify the proper authorities and ad- vise those responsible for monitoring proprietary and/or central station alarms. Step 11.Once a week after a valve is reset following an operational test or system operation, the Low Body Drain Valve (and any low point drain valves) should be partially opened (and then subsequently closed) to relieve drain- back water. Continue this procedure until drain-back water is no longer pre- sent. Care and Maintenance The following procedures and inspec- tions should be performed as indi- cated, in addition to any specific re- quirements of the NFPA, and any impairment must be immediately cor- rected. The owner is responsible for the in- spection, testing, and maintenance of their fire protection system and de- vices in compliance with this docu- ment, as well as with the applicable standards of the National Fire Protec- tion Association (e.g., NFPA 25), in addition to the standards of any authority having jurisdiction. The in- stallingcontractor orproductmanufac- turer should be contacted relative to any questions. It is recommended that automatic sprinkler systems be inspected, tested, and maintained by a qualified Inspection Service. NOTES The operational test procedure and waterflow pressure alarm test proce- dure will result in operation of the as- sociated alarms. Consequently, notifi- cation must first be given to the owner and the fire department, central sta- tion,orothersignalstationtowhichthe alarms are connected. Before closing a fire protection system main control valve for maintenance work on the fire protection system that itcontrols,permissiontoshutdownthe affected fire protection systems must first be obtained from the proper authorities and all personnel who may be affected by this decision must be notified. Annual Operation Test Procedure Proper operation of the DPV-1 Valve (i.e., opening of the DPV-1 Valve dur- ing a fire condition) should be verified at least once a year as follows: Step 1.If water must be prevented from flowing beyond the riser, perform the following steps. •Close the Main Control Valve. •Open the Main Drain Valve. •Open the Main Control Valve one turn beyond the position at which water just begins to flow from the Main Drain Valve. •Close the Main Drain Valve. Step 2.Open the system’s Inspector’s Test Connection. Step 3.Verify that the DPV-1 Valve has operated, as indicated by the flow of water into the system and that all waterflow alarms operate properly. Step 4.Close the system’s Main Con- trol Valve. Step 5.Reset the DPV-1 Valve in ac- cordancewiththeValveSettingProce- dure. NOTE It is recommended that the require- ment of NFPA 25 to annually inspect the inside of the valve be performed at this time and prior to resetting the DPV-1 Valve. Refer to the Automatic Drain Valve Inspection sub-section Steps 2 through 5 for instructions with regard to the inspection of the Clapper Facing. Quarterly Waterflow Alarm Test Procedure Testing of the system waterflow alarms should be performed quarterly. To test the waterflow alarm, open the Alarm Test Valve, which will allow a flow of water to the Waterflow Pres- sure Alarm Switch and/or Water Motor Alarm. Upon satisfactory completion of the test, close the Alarm Test Valve. Water Pressure Inspection The Water Pressure Gauge is to be inspected monthly (per NFPA 25) to ensure that normal system water pres- sure is being maintained. Air Pressure Inspection The Air Pressure Gauge is to be in- spected monthly (per NFPA 25) to en- sure that normal system air pressure is being maintained. Automatic Drain Valve Inspection The Automatic Drain Valve should be inspected monthly (per NFPA 25) by depressing the plunger and checking to ensure that the Automatic Drain Valve is not discharging water and/or air. A discharge of water and/or air is an indication that the air and/or water seats are leaking, which could sub- sequently cause a false operation should the intermediate chamber be- come inadvertently pressurized. If leakage is present, take the DPV-1 Valve out of service (i.e., close the main control valve, open the main drain valve,closetheairsupplycontrol valve, remove the Dry Pipe Valve Ac- celerator from service, as applicable, in accordance with its Technical Data Sheet (Refer to TFP1100 for the QRS or TFP1112 for the ACC-1), and open the Inspector’s Test Connection to re- lieve the system air pressure to 0 psig as indicated on the System Air Pres- sure Gauge), and then after removing Page 17 of 20 TFP1020 the Handhole Cover, perform the fol- lowing steps: Step 1.Make sure that the Seat Ring is clean and free of any nicks or signifi- cant scratches. Step 2.Remove the Clapper Assem- bly from the valve by first pulling out the Hinge Pin. Step 3.Disassemble the Clapper Fac- ing Retainer from the Clapper so that the Clapper Facing can be removed and inspected. Make sure that the Clapper Facing does notshow signs of compression set, damage, etc. Re- place the ClapperFacingifthereisany signs of wear. Step 4.Clean the Clapper Facing, Clapper,andClapperFacingRetainer, and then reassemble the Clapper As- sembly. Step 5.Reinstall the Clapper Assem- bly with its Hinge Pin and then reinstall the Handhole Cover.
