General The Reliable Model DDX Deluge Valve is a hydraulically operated, differential latching clapper-type valve designed for use as primary control valve in deluge, preaction, or special types of fire protection systems. Following operation, the valve is easily reset externally (see Fig.). The Wet Pilot Line Trim set is connected to the push rod chamber outlet and provides a one and one quarter inch main drain on (50mm), ½ (65mm), 76mm and (80mm) valve sizes or a two inch main drain on 4 (00mm), 65mm, 6 (50mm) and 8 (00mm) valve sizes, alarm test, supply pressure gauge, and the push rod chamber supply connections. Releasing devices that can be used are wet pilot line detectors (Model F-FTR) or hydraulic manual emergency stations/pull boxes (Models A & B). Two alternate actuation trim sets, Dry Pilot Line or Electric Actuation, are available when dry pilot sprinklers or solenoid valves are used for releasing. Actuation by solenoid valves enables a full range of electrical detectors to be used for remote sensing. Listings & Approvals: (Only when used with Reliable s Trim Sets.).

VdS Schadenverhütung GmbH Valve Operation The Reliable Model DDX Deluge Valve is shown in both closed and open positions in Fig.. In the closed position, the supply pressure acts on the underside of the clapper and also on the push rod through the push rod chamber s inlet restriction. The resultant force due to the supply pressure acting on the push rod is multiplied by the mechanical advantage of the lever and is more than sufficient to hold the clapper closed against normal supply pressure surges. When a fire is detected, a releasing device vents the push rod chamber to atmosphere through the chamber s outlet. Since the pressure cannot be replenished through the inlet restriction as rapidly as it is vented, the push rod chamber pressure falls instantaneously. When the push rod chamber pressure approaches approximately one-third of the supply pressure, the upward force of the supply pressure acting beneath the clapper overcomes the lever-applied force thereby opening the clapper. Once the clapper has opened, the lever acts as a latch, preventing the clapper from returning to the closed position. Water from the supply flows through the Deluge Valve into the system piping. Water also flows through the Deluge Valve alarm outlet to the alarm devices. After system shutdown, resetting the Model DDX Deluge Valve is quite simple. Doing so only requires pushing in and turning the reset knob at the rear of the valve (see Fig.). The external reset feature of the Model DDX Deluge Valve provides a means for simple, economical system testing, which is one essential facet of a good maintenance program. The external reset feature does not, however, eliminate another important facet of good maintenance, namely, periodic cleaning and inspection of the internal valve parts. In the event that water builds up inside the valve due to condensate from the air supply system or water left inside from valve system testing, a drain is available for venting. After closing the main supply valve, a small valve over the drain cup can be opened slightly until the water inside the valve body and the main pipe column has drained. Whenever ambient temperature conditions are high, the water temperature in the Model DDX Deluge Valve s pushrod chamber could possibly increase, thereby increasing the pressure in the chamber to values exceeding the rated pressure of the system. In an indoor installation where standard room temperatures are exceeded, a pressure relief kit may be needed. Pressure relief kit, P/N 65005000, can be installed into the pushrod chamber s release line to limit the pressure to 50 psi (7, bar). Reliable Model DDX Deluge Valve with associated trim sizes (50 mm), ½ (65 mm), 76 mm, (80 mm), 4 (00 mm), 65 mm, 6 (50 mm) and 8 (00 mm) are rated for use at a minimum water supply pressure of 0 psi (,4 bar) and a maximum water supply pressure of 50 psi (7, bar) for (50mm), / (65mm), (80mm), 76mm and 8 (00mm) valve sizes and 00 psi (0,7 bar) for 4 (00mm), 6 (50mm) and 65mm valve sizes). Water supplied to the inlet of the valve and to the push rod chamber must be maintained between 40 F(4 C) and 40 F(60 C). Pressurizing Line Connection The water supply for the push-rod chamber must be provided by connection of its inlet pressurizing line to the water supply piping. Pressurizing lines for multiple Model DDX Deluge Valve push-rod chambers must never be manifolded together, having only a single tap on the water supply piping. Each Model DDX Deluge Valve must have its own push-rod chamber pressurizing line connection. This connection must be made on the supply side of the water supply control valve (see Fig. 4 or Fig. 5). This can be accomplished by: Using a tapped connection directly below or next to the main water supply control valve using a welded outlet or the appropriate mechanical fittings. A grooved-end outlet coupling is one way to achieve this; or Using a water supply control valve that has an available threaded (NPT) supply-side tap design to allow for a direct water supply connection to the Model DDX Deluge Valve s push-rod chamber. Caution: Reliable s DDX valve is designed with an inlet restriction built into the pushrod chamber. It is important not to introduce additional restrictions into the direct water supply connection or the discharge from the pushrod chamber by installing additional valves or improperly installing the copper lines used in the trim of the valve..

Fig. Hydrostatic Testing of DDX Valves and DDX Systems As required by NFPA, fire sprinkler systems with working pressures up to and including 50 psi are to be hydrostatically tested at a water pressure of 00 psi and maintain that pressure without loss for two hours. Fire sprinkler systems with working pressures above 50 psi are required to be hydrostatically tested at 50 psi above the system working pressure and maintain that pressure without loss for two hours. In addition to the hydrostatic tests described above, dry pipe and double interlock preaction systems require an additional low pressure air test. In some cases, hydrostatic testing (in accordance with the NFPA requirements noted above) will result in pressures that exceed the working pressure of the valve and trim kit for the two-hour test period. The valve and applicable trim kit have been tested, approved and listed under these conditions and as such, hydrostatic testing in accordance with NFPA is acceptable. In addition, the clapper can remain in the closed position and the trim kit need not be isolated, as each has been designed to withstand hydrostatic testing as required by NFPA. Hydrostatically testing the valve and trim to pressures higher than their rating is limited to the hydrostatic test as referenced by NFPA. It does not address the occurrence(s) of a water hammer effect, which can indeed damage the valve. A water hammer in the water supply piping of the valve can create pressures in excess of the rated pressure and should be avoided by all necessary means. This condition may be created from improper fire pump settings, underground construction work, or an improper venting of trapped air in the water supply piping.

Installation position: Vertical Trim Descriptions The trims for the Reliable Model DDX Deluge Valve are arranged for rapid, easy, and compact attachment, and serve as connection points to Reliable Model C Mechanical Alarms and other devices. The available Model DDX Deluge Valve trim sets are: Wet Pilot Trim Dry Pilot Trim Electric Actuation Trim All three trim configurations can be ordered as individual parts, in time-saving segmentally assembled kit forms, or fully assembled to the Model DDX Deluge Valve (with or without a control valve). The Model B Hydraulic Manual Emergency Station (see Fig. 9) is a standard item of all Deluge Valve trim sets. It consists of an aluminum nameplate mechanically attached to a ball valve. The valve handle in its OFF position is guarded against accidental turning to the ON position (and system discharge) by a nylon cable tie provided with each trim kit. The cable tie is inserted, as shown in Fig. 9, after the system has been restored for operation. The nylon cable tie is designed to allow, in case of an emergency, forceful turning of the valve handle to the ON position. As an alternative to the Model B Hydraulic Manual Emergency Station, the Model A Hydraulic Manual Emergency Pull Box (see Bulletin 506) is also available and can be provided as an option. Model F-FTR fixed temperature pilot line detectors and spacing requirements are described in Bulletin 80. Wet Pilot Line Trim Wet pilot line operation is the simplest method of Deluge Valve Actuation. The trim is a basic one and its components are included in all other Reliable Model DDX Deluge Valve Trims regardless of application. Shown in Figures 4 & 5, it contains components required on all installations, such as a one and one quarter main drain on (50 mm), ½ (65 mm), 76 mm and (80 mm) valve sizes or a two inch main drain on 4 (00 mm), 65 mm, 6 (50 mm) and 8 (00 mm) valve sizes, alarm test, supply and push rod chamber pressure gauges, and push rod chamber connections. The wet pilot line consists of a line of closed detectors (Model F-FTR) located over the area to be protected. This line contains water under pressure and is connected to the outlet of the push rod chamber of the Deluge Valve. When one of the pilot line detectors actuates, the push rod chamber is vented and the Deluge Valve operates. The Deluge Valve can also be operated manually by opening the ball

Dry Pilot Line Trim Dry pilot line operation is used in areas which are subject to freezing conditions or to obtain installed sprinkler heights and pipe lengths greater than allowed for wet pilot line trim. Dry pilot operation uses a pilot line of closed sprinklers (Model F-FTR) containing air under pressure located in the area to be protected. This pressurized line is connected to a Model LP Dry Pilot Line Actuator. The dry pilot line actuator functions very much like a miniature dry pipe valve. In areas where moisture-laden air could cause freezing or other problems in the dry pilot line, the use of a cylinder of dry compressed gas such as nitrogen is suggested. Approved gas handling regulators and connections are then recommended. When one of the closed sprinklers on the dry pilot line actuates, the air pressure is reduced, thus opening the Model LP Dry Pilot Line Actuator, which releases the Deluge Valve. NFPA 7 or the Authority Having Jurisdiction should be consulted for spacing and elevation requirements of the pilot line sprinklers. The Dry Pilot Line Trim, shown in Figures 7 and 8, includes gauges to read the air and water pressure, a low air pressure switch, a pressure relief valve, a Model LP Dry Pilot Line Actuator, and connections for the dry pilot line of detectors. Dry Pilot Line Trim installation on Model DDX Deluge Valves uses eight tapped openings for trim connections. Each opening and its function are indicated on Fig. 7 and Fig. 8. Using Fig. 7 and Fig. 8 as reference, the recommended trim installation is as follows:. Install ½ nipple (#9, Fig. 7 or #4, Fig. 8) in tapped opening marked TEST. Note: If interference occurs between the supply gauge and the control valve, the /4 plug (#57, Fig. 7 or #58, Fig. 8) in the opening marked SUPPLY may be swapped with: the /4 nipple (#7, Fig. 7), angle valve (#, Fig. 7) and gauge (#7, Fig. 7) for the (50mm), -/ (65mm), 76mm and (80mm) valve sizes; /4 nipple (#7, Fig. 8), /4 elbow (#7, Fig. 8), /4 nipple (#8, Fig. 8), -way valve (#69, Fig. 8) and the gauge (#7, Fig. 8) for the 4 (00mm), 65mm and 6 (50mm) valve sizes; /4 nipple (#8, Fig. 8), -way valve (#69, Fig. 8) and the gauge (#7, Fig. 8) for the 8 (00mm) valve size, in the trim installed in the opening marked TEST.. Install ½ nipple (#4, Fig. 7 or #9, Fig. 8) in tapped opening marked ALARM and connect balance of this trim line.. Install ¼ plug (#57, Fig. 7 or #58, Fig. 8) in tapped opening marked SUPPLY. Note: If interference occurs between the supply gauge and the control valve, the /4 plug (#57, Fig. 7 or #58, Fig. 8) in the opening marked SUPPLY may be swapped with: the /4 nipple (#7, Fig. 7), angle valve (#, Fig. 7) and gauge (#7, Fig. 7) for the (50mm), -/ (65mm), 76mm and (80mm) valve sizes; /4 nipple (#7, Fig. 8), /4 elbow (#7, Fig. 8), /4 nipple (#8, Fig. 8), -way valve (#69, Fig. 8) and the gauge (#7, Fig. 8) for the 4 (00mm), 65mm and 6 (50mm) valve sizes; /4 nipple (#8, Fig. 8), -way valve (#69, Fig. 8) and the gauge (#7, Fig. 8) for the 8 (00mm) valve size, in. the trim installed in the opening marked TEST. 4. Install ½ nipple (#8, Fig. 7 or #9, Fig. 8) in tapped opening marked OUT and connect balance of this trim line. 5. Install ¼ inline check valve (#8, Fig. 7 or #7, Fig. 8) in tapped opening marked IN and connect balance of this trim line. Caution: Over tightening check valve can cause a restriction in flow that may prevent the valve from setting up. 6. Install ¼ Nipple (#47, Fig. 7) or nipple (#48, Fig. 8) in tapped drain opening and connect balance of this trim line. 7. Install ¾ x ¼ reducing bushing (#5, Fig. 7 or #5, Fig. 8) in the lower-most tapped opening at the rear of the Deluge Valve and connect the balance of this trim line. 8. Install ¾ pipe plug (#59, Fig. 7 or #60, Fig. 8) in the upper-most tapped opening at the rear of the Deluge Valve. Connect the air supply to the air inlet side of the Model LP Dry Pilot Line Actuator as shown in Fig. 7 or Fig. 8. Table A specifies the air pressure to be used in a dry pilot line. The level of air pressure is adjusted by removing the cap nut on the end of the Relief Valve (#55, Fig. 7 or #56, Fig. 8) and turning the now exposed slotted adjusting screw clockwise to increase pressure or counterclockwise to reduce it. Replace the cap nut after the correct pressure setting has been made at 5 psi above the maximum pilot line pressure required by Table A. An appropriate automatic pressure maintenance device must be used to safeguard against the Deluge Valve tripping due to air pressure leaks in the dry pilot line. See Bulletin 54 for pressure maintenance device information. Install the dry pilot line as required. Wire the low air pressure switch (#5, Fig. 7 or #5, Fig. 8) to an annunciating device or control panel. This low air pressure switch should be set to open at an air pressure which is slightly lower than the Not Less Than values found in Table A.

Electric Actuation Trim Electric Actuation trim (see Figures 0 and ) combines a normally closed/powered-open solenoid valve with the Wet Pilot Trim for releasing the Deluge Valve. The solenoid valve used in the assembly is available in both a 75 psi (, bar) or 00 psi (0,7 bar) rating. Details on the electrical portion of this trim can be found in Reliable Bulletin 700, which describes Deluge and Preaction Systems. Caution: Repairs or disassembly of the solenoid valve should only be done by a trained technician. An improperly repaired or partially assembled solenoid valve could result in failure of the valve to operate. Electric Actuation Trim installation on Model DDX Deluge Valves uses eight tapped openings for trim connections. Each opening and its function are indicated on Fig. 0 or Fig.. Using Fig. 0 or Fig. as reference, the recommended trim installation is as follows:. Install ½ nipple (#5, Fig. 0 or #9, Fig. ) in tapped opening marked TEST. Note: If interference occurs between the supply gauge and the control valve, the /4 plug (#50, Fig. 0 or #5, Fig. ) in the opening marked SUPPLY may be swapped with: the /4 nipple (#, Fig. 0), angle valve (#0, Fig. 0) and gauge (#6, Fig. 0) for the (50mm), -/ (65mm), 76mm and (80mm) valve sizes; /4 nipple (#4, Fig. ), /4 elbow (#5, Fig. ), /4 nipple (#5, Fig. ), -way valve (#6, Fig. ) and the gauge (#64, Fig. ) for the 4 (00mm), 65mm and 6 (50mm) valve sizes; /4 nipple (#5, Fig. ), -way valve (#6, Fig. ) and the gauge (#64, Fig. ) for the 8 (00mm) valve size, in the trim installed in the opening marked TEST.. Install ½ nipple (#7, Fig. 0 or #6, Fig. ) in tapped opening marked ALARM and connect balance of this trim line.. Install ¼ plug (#50, Fig. 0 or #5, Fig. ) in tapped opening marked SUPPLY. Note: If interference occurs between the supply gauge and the control valve, the /4 plug (#50, Fig. 0 or #5, Fig. ) in the opening marked SUPPLY may be swapped with: the /4 nipple (#, Fig. 0), angle valve (#0, Fig. 0) and gauge (#6, Fig. 0) for the (50mm), -/ (65mm), 76mm and (80mm) valve sizes; /4 nipple (#4, Fig. ), /4 elbow (#5, Fig. ), /4 nipple (#5, Fig. ), -way valve (#6, Fig. ) and the gauge (#64, Fig. ) for the 4 (00mm), 65mm and 6 (50mm) valve sizes; /4 nipple (#5, Fig. ), -way valve (#6, Fig. ) and the gauge (#64, Fig. ) for the 8 (00mm) valve size, in the trim installed in the opening marked TEST. 4. Install ½ nipple (#4, Fig. 0 or #6, Fig. ) in tapped opening marked OUT and connect balance of this trim line. 5. Install ¼ inline check valve (#6, Fig. 0 or #5, Fig. ) in tapped opening marked IN and connect balance of this trim line. Supply line must be connected to the inlet of the control valve for each Deluge Valve as shown. Caution: Over tightening check valve can cause a restriction in flow that may prevent the valve from setting Fig. 9 up. 6. Install ¼ Nipple (#4, Fig. 0) or nipple (#44, Fig. ) in tapped drain opening and connect balance of this trim line. 7. Install ¾ x ¼ reducing bushing (#46, Fig. 0 or #48, Fig. ) in the lower-most tapped opening at the rear of the Deluge Valve and connect the balance of this trim line. 8. Install ¾ pipe plug (#5, Fig. 0 or #54, Fig. ) in the upper-most tapped opening at the rear of the Deluge Valve Maintenance Reliable Deluge Valves and associated equipment shall periodically be given a thorough inspection and test. NFPA 5 provides minimum requirements for inspection, testing and maintenance. The Deluge Valve should be tested, operated, cleaned, and inspected at least annually and parts replaced as required. 8.

Resetting Model DDX Deluge Valve Systems Refer to Figs. 7, 8,, & 4.. Close the valve controlling water supply to the Deluge Valve and close valve A (Fig. 4).. Open main drain valve B (Fig. 4) and drain system.. Open all drain valves and vents at low points throughout the system, closing them when flow of water has stopped. Open valve D (Fig. 4). 4. With valve G (Fig. 4) open, push in the plunger of ball drip valve E (Fig. 4), forcing the ball from its seat to verify that there is atmospheric pressure inside the main valve chamber. 5. Push in and rotate external reset knob (#4, Fig. or #8, Fig. ) clockwise, until you hear a distinct noise indicating that the clapper has reset. 6. Inspect and replace any portion of the detection system subjected to fire conditions. 7. Open valve A (Fig. 4) and allow water to fill the push rod chamber. Close valve D (Fig. 4). 8. Bleed all air from the actuation piping. A. Wet Pilot Trim bleed the entire wet pilot line until all air is removed at the most remote sprinkler. B. Electric Actuation Trim open the solenoid valve by operating a detector or an electric manual emergency station. While water is flowing through the solenoid valve, cause it to close. Refer to Bulletin 700, Special Hazards & Special Systems for details. C. Dry Pilot Trim open valve D (Fig. 4) allowing water to flow through the pilot line actuator. When all air has been expelled from the release line, and there is a solid flow of water into the drain cup J (Fig. 4), apply compressed air or nitrogen through the pressure maintenance device to close the pilot line actuator. Subsequently, close valve D (Fig. 4) and adjust the air or nitrogen pressure to the appropriate value in Table A as indicated on air pressure gauge (#7, Fig. 7 or #7, Fig. 8). 9. Check that valves D (Fig. 4) and F (Fig. 4) are closed and that valve G is open (Fig. 4). Open slightly the valve controlling water supply to the Deluge Valve, closing the main drain valve B (Fig. 4) when water flows. Observe if water leaks through ball drip valve E (Fig. 4), into drain cup J (Fig. 4), (Be sure that valve G (Fig. 4) is open). If no leak occurs the water seat is tight. Open slowly but fully the valve controlling water supply to the Deluge Valve. Verify that it is fully opened and properly monitored. 0. Valve A (Fig. 4) must remain open when the Deluge Valve has been reset, to maintain water pressure in the push rod chamber.. Verify that the Model B Manual Emergency Station, valve D (Fig. 4) is sealed in the OFF position with the appropriate nylon tie. Inspection and Testing Refer to Figs., & 4.. Water supply be sure the valves controlling water supply to the Deluge Valve are opened fully and properly monitored.. Alarm line be sure that valve G (Fig. 4) is opened and remains in this position.. Other trimming valves check that valve A (Fig. 4) is open, as well as all of the pressure gauge s ¼ -way valves. Valves D, F, & H (Fig. 4) should be closed. 4. Ball drip valve E (Fig. 4) Make sure valve G (Fig. 4) is open. Push in on the plunger to be sure ball check is off its seat. If no water appears, the Deluge Valve s water seat is tight. Inspect the bleed hole (see Fig. of Fig. ) on the underside of the push rod chamber for leakage. 5. Dry pilot trim check air gauge pressure for conformance to Table A. 6. Releasing device check outlet of the releasing device (i.e., the dry pilot line actuator, solenoid valve, or the hydraulic manual emergency station) for leakage. Also verify that tubing drain lines from releasing devices are not pinched or crushed which could prevent proper releasing of the Deluge Valve. 7. Testing alarms Make sure valve G (Fig. 4) is open. Open valve F (Fig. 4) permitting water from the supply to flow to the electric sprinkler alarm switch and to the mechanical sprinkler alarm (water motor). After testing, close this valve securely. Push in on the plunger of ball drip valve E (Fig. 4) until all of the water has drained from the alarm line. 8. Operation test Open the Model B Manual Emergency Station, valve D (Fig. 4). Note: An operational test will cause the Deluge Valve to open and flow water into the sprinkler system. 9. Secure the Model B Manual Emergency Station, valve D (Fig. 4), in the OFF position with nylon tie after Deluge Valve is reset. Testing Detection System Without Operating Deluge Valve Refer to Figs. 7, 8 & 4.. Close the valve controlling water supply to Deluge Valve and open the main drain valve B (Fig. 4).. Verify that valve A (Fig. 4) is open, allowing water to enter the push rod chamber.. Operate detection system A. Wet Pilot Trim open Model B Manual Emergency Station, valve D (Fig. 4). B. Dry Pilot Trim directly above the Model LP Dry Pilot Line Actuator, remove the ¼ pipe plug (#58, Fig. 7 or #59, Fig. 8) and open the ¼ three-way valve (#70, Fig. 7 or #70, Fig. 8). C. Electric Actuation refer to Bulletin 700. 4. Operation of the detection system must result in a sudden drop of water pressure in the push rod chamber. 5. Reset detection system reverse operations performed in step three above and then proceed according to the directions listed in the Resetting Model DDX Deluge Valve Systems section of this bulletin for resetting the Deluge Valve. 7.

Draining Excess/Condensate Water From System Refer to Fig. 4. Close the valve controlling water supply to Deluge Valve. Also close valve A and open main drain valve B.. Open condensate drain valve H until all water has drained. Close valve H.. Close main drain valve B. If system contains pressurized air, allow air pressure to come back up to specification (see table A). Open valve A and the valve controlling the water supply to the Deluge Valve. Maintenance Procedures - Model DDX Deluge Valve Refer to Figs. 7, 8,,, & 4.. Mechanical sprinkler alarm (water motor not shown) not operating: This is most likely caused by a clogged screen in the strainer of the water motor. Proceed as follows: Remove plug from the strainer. Remove and clean the screen. Replace the screen and the plug, and then tighten securely (Ref. Bulletin 6).. Leakage out of the ball drip valve E (Fig. 4). a. Water leakage due to water column in deluge systems: This condition can be caused by leakage past the system side of the Model DDX Deluge Valve s seal assembly (#8, Fig. or #5, Fig. ). Be sure that this surface is free of any type of debris. To eliminate leakage due to water column in a deluge system, refer to the section in this bulletin marked Draining Excess/Condensate Water From System. If the problem continues proceed to the following section. b. Leakage, air or water from the ball drip valve, E (Fig. 4): If system air is leaking out the ball drip valve, the problem is either damage to the airside of the Model DDX Deluge Valve s seal assembly (#8, Fig. or #5, Fig. ), seat (#9, Fig. or #, Fig. ), the upper seat o-ring(#, Fig. or #, Fig. ) or, on the 8 (00 mm) valve size only, the mounting ring o-ring (#, Fig. ). If supply water is leaking out the ball drip valve, the problem could be caused by damage to the Model DDX Deluge Valve s seal assembly (#8, Fig. or #5, Fig. ), seat (#9, Fig. or #, Fig. ), or lower seat O-ring (#4, Fig. or #, Fig. ). The following section provides instructions to correct both conditions: A) Shut down the valve controlling the water supply to the Deluge Valve and open the ¼ main drain valve on the (50mm), ½ (65mm), 76mm and (80mm) valve sizes or the main drain valve on the 4 (00mm), 65mm, 6 (50mm) and 8 (00mm) valve sizes, valve B (Fig. 4). Open the water column drain valve H (Fig. 4). Close the pushrod chamber supply valve A (Fig. 4) and open the Model B Manual Emergency Station, valve D (Fig. 4). B) Remove the Deluge Valve s front (handhold) cover (#7, Fig. or #4, Fig. ) and inspect the 8. seat (#9, Fig. or #, Fig. ), clapper (#6, Fig. or #, Fig. ), and seal assembly (#8, Fig. or #5, Fig. ) for damage. If inspection indicates damage to the seal assembly (#8, Fig. or #5, Fig. ), replace as follows: For Valve Sizes: (50mm), ½ (65mm), 76mm, (80mm), 8 (00mm) and 4 (00mm), 6 (50mm) & 65mm with Screw- In Seat only, Refer to Fig. 7, Fig. 8 & Fig. : Remove the bumpstop nuts (#0, Fig. ) and remove the seal assembly (#8, Fig. ). Install a new seal assembly (#8, Fig. ) and thread the bumpstop nuts (#0, Fig. ) onto the threaded studs of the seal assembly (#8, Fig. ) and tighten finger tight plus ¼ to ½ turn. If inspection indicates damage to the clapper (#6, Fig. ) only, then the clapper subassembly can be removed as follows: At the rear of the valve, disconnect the water column drain trim section starting with the elbow connector (#, Fig. 7 or #, Fig. 8). Then remove the ¼ globe valve (#, Fig. 7 or #, Fig. 8), followed by the ¾ x¼ reducing bushing (#5, Fig. 7 or #5, Fig. 8). Remove the retaining ring (condensate drain side for (50mm), ½ (65mm), (80mm), 76mm and 8 (00mm) valve sizes or hand hole cover side for 4 (00mm), 6 (50mm) and 65mm valve sizes) from the clapper hinge pin (#0, Fig. ) and push this pin through the hand hole opening (for (50mm), ½ (65mm), (80mm), 76mm and 8 (00mm) valve sizes or condensate drain side for 4 (00mm), 6 (50mm) and 65mm valve sizes) and remove the clapper subassembly. Replace the seal assembly as described previously. Inspect the clapper (#6, Fig. ) visually before reinstalling. Reinstall in the reverse order making sure the clapper spacers are in their proper position. If the seat (#9, Fig. ) is damaged or it is suspected that the leakage is through the lower O-ring (#4, Fig. ), the seat-clapper subassembly is easily removed as a unit as follows: Using Reliable P/N 68860000 Seat Wrench for (50mm), ½ (65mm), 76mm and (80mm) valve sizes, Reliable P/N 688604000 for 4 (00mm) valve size, Reliable P/N 688606000 for the 6 (50mm) and 65mm valve sizes or Reliable P/N 688608000 Seat Wrench for 8 (00mm) valve size, remove the seat by unscrewing. This will loosen the seatclapper-mounting ring subassembly. Reach into the valve and grasp the seat and remove it from the valve. Then remove the clappermounting ring subassembly from the valve. Visually examine all components of the seatclapper-mounting ring subassembly replacing any component that appears damaged. New O-rings (# & #4, Fig. and #, Fig. (8

(00mm) valve size only)) should always be used for reassembly. For Valve Sizes: 4 (00mm), 65mm, 6 (50mm) with Drop-In Seat Configuration only, Refer to Fig. 8 and Fig. : At the rear of the valve, disconnect the water column drain trim section starting with the elbow connector (#, Fig. 8). Then remove the ¼ angle globe (#, Fig. 8), followed by the ¾ x¼ reducing bushing (#5, Fig. 8). Remove the retaining ring (hand hole cover side) from the clapper hinge pin (#4, Fig. ) and push this pin through the condensate drain port and remove the clapper subassembly. Remove the four retaining screws (#4, Fig. ) holding the seal faceplate assembly (#5, Fig. ). Inspect the clapper (#, Fig. ) visually before installing. Apply a small amount of silicone based lubricant to the four retaining screws. Install a new seal faceplate assembly. Torque the retaining screws to approximately 40 inchpounds and reassemble. If the seat (#, Fig. ) is damaged or it is suspected that the leakage is through the lower o-ring (#, Fig. ), the seat-clapper subassembly is easily removed as a unit as follows: Using a 5/6 Allen wrench, remove the two /8 NPT pipe plugs (#9, (not shown) Fig. ) located on the side chamber side of the Model DDX deluge valve. The seat-clapper subassembly is retained by two locking pins (#7, (not shown) Fig. ). The centers of these pins have a ¼ -0 threaded hole. Remove the two locking pins by engaging them with a ¼ -0 screw and pulling them out (the two locking pins are not externally threaded, so turning them with the attached ¼ -0 screw or threaded rod is not recommended. A proven method is to use ¼ -0 threaded rod with a locknut on the unassembled end. Grab hold of the locknut with a pliers or vise-grips and tap the pliers or vise-grips in the direction away from the Deluge Valve. Doing so should pull the locking pins out of the Deluge Valve. With the clapper (#, Fig. ) in the closed position (not latched), dislodge the clapper-seat subassembly from the valve body by inserting two slotted screwdrivers under the lever and clapper mounting ears and pry up until the clapper-seat subassembly is free from its bore. Reach into the valve and grasp the clapper-seat subassembly from the sides. Making sure the clapper is in the closed position (see Fig. ), lift up and rotate the clapper-seat sub assembly clockwise 90 degrees so that the lever side of the assembly is facing up towards the outlet of the deluge valve. Next, rotate the clapper-seat sub assembly 90 degrees about the centerline of the valve so that the clapper is facing the hand hole open- ing and the lever is still facing the outlet of the deluge valve.. Then rotate the clapper-seat sub assembly 90 degrees, so that the clapper is now facing the outlet of the deluge valve and the lever is now facing the back of the valve. Pull the clapper-seat sub assembly out through the hand hole opening by the hinge pin side. Rotating the seat-clapper subassembly up as it is being removed will help it slide out more easily since the lever will prohibit it from sliding straight out. Visually examine all components of the clapper-seat subassembly replacing any component that appears damaged. New o- rings (#, Fig. ) should always be used for reassembly. Reassembly: For Valve Sizes: (50mm), ½ (65mm), 76mm, (80mm), 8 (00mm) and 4 (00mm), 6 (50mm) & 65mm with Screw- In Seat Configuration only, Refer to Fig. : Clean the bore of the valve body. Lubricate the bore with O-ring grease. Lubricate and install the O-rings (# & #4, Fig. ) onto the seat. Lubricate and install the mounting ring o-ring (#, Fig. ) into the body (8 (00mm) valve size only). Insert the clapper-mounting ring subassembly into the handhold opening of the Deluge Valve using caution to not damage or dislodge the mounting ring o-ring (#, Fig. ) (8 (00mm) valve size only). Align the mounting ring so that the Lever (#5, Fig. ) is near the pushrod (#5, Fig. ) and the mounting ring (#5, Fig. ) ears are between the tabs of the valve body (#, Fig. ). Insert the seat (#9, Fig. ) into the valve body (#, Fig. ) and through the clapper-mounting ring subassembly. Start to tread the seat (#9, Fig. ) into the body by hand, then tighten the seat (#9, Fig. ) with Reliable P/N 68860000 Seat Wrench for (50mm), ½ (65mm), 76mm and (80mm) valve sizes, Reliable P/N 688604000 Seat Wrench for 4 (00mm) valve size, Reliable P/N 68806000 Seat Wrench for 6 (50mm and 65mm valve sizes or Reliable P/N 688608000 Seat Wrench for 8 (00mm) valve size until it bottoms out on the mounting ring (#5, Fig. ).Verify that the seat-clappermounting ring subassembly is in the fully down position between the tabs of the body, and check to see that the lever (#5, Fig. ) lines up with the push rod (#5, Fig. ). Loosen and reassemble if necessary. Reassemble the handhold cover (#7, Fig. ) and set up the Model DDX Deluge Valve as per the section Resetting Model DDX Deluge Valve Systems. For Valve Sizes: 4 (00mm), 65mm, 6 (50mm) with Drop-In Seat Configuration only, Refer to Fig. : It is likely that the lower seat o-ring (#, Fig. ) 9.

has remained at the bottom of the Deluge Valve body s bore. Discard this o-ring and clean the bore. Lubricate the bore with o-ring grease and place the lower o-ring on the step at the bottom of the bore, verifying that it is in full contact with the bore. Lubricate the bottom step and upper o-ring (#, Fig. ) of the refurbished clapperseat subassembly. Insert the clapper-seat sub assembly into the hand hole opening, lever (#7, Fig. ) first and rotating the clapper-seat subassembly until the lever faces the outlet of the deluge valve. Next rotate the clapper-seat subassembly 90 degrees about the center axis of the valve until the bottom of the clapper-seat sub assembly faces the pushrod (#0, Fig. ). Then rotate the clapper-seat subassembly 90 degrees counterclockwise so that the clapper (#, Fig. ) is facing the outlet of the deluge valve and the lever (#7, Fig. ) is facing the pushrod (#0, Fig. ). Once the clapper seat subassembly is in this position simply slide the assembly into the bore of the valve, making sure it is straight to avoid binding of the seat in the bore. Slightly twisting the assembly will assist in getting the clapper-seat subassembly properly seated. Once it is verified that the clapper-seat sub assembly is in the fully down position and the lever (#7, Fig. ) is aligned with the pushrod (#0, Fig. ), clean and lubricate the two locking pins (#7, (not shown) Fig. ) with o-ring lubricant. Slide the two locking pins into the deluge valve body to lock the seat in place. Slightly twisting and pressing down on the clapper-seat subassembly will help the pins to slide in more easily. Then reinstall the /8 NPT pipe plugs (#9, (not shown) Fig. ). Reassemble the hand hole cover (#4, Fig. ) and set up the Model DDX Deluge Valve as per the section Resetting Model DDX Deluge Valve Systems.. Leakage out of the push rod chamber vent hole: A small bleed hole is located on the underside of the push rod chamber (see Fig. or Fig. ). If there is air or water leakage coming out of this hole, do the following: a) Shut down the valve controlling water supply to the Deluge Valve. Relieve the inlet pressure by opening the ¼ main drain valve on the (50mm), ½ (65mm), 76mm and (80mm) valve sizes or the main drain valve on the 4 (00mm), 65mm, 6 (50mm) and 8 (00mm) valve sizes, valve B (Fig. 4). Close valve A (Fig. 4) that supplies water to the push rod chamber, and open the Model B Manual Emergency Station, valve D (Fig. 4). b) Remove the trim at the unions nearest to the push rod chamber cover (#, Fig. or #8, Fig. ). c) Take the push rod chamber cover (#, Fig. or #8, Fig. ) off by removing the six retaining screws (#6, Fig. or #9, Fig. ). CONDITION ONE (Water coming out of the bleed hole): Water coming out of the bleed hole is caused by a leaking diaphragm (#8, Fig. or #4, Fig. ). Visually inspect the push rod chamber cover (#, Fig. or #8, Fig. ), piston (#7, Fig. or #8, Fig. and bore of the body (#, Fig. or #, Fig. ) to determine what could have damaged the diaphragm and correct. Install a new diaphragm. NOTE: The diaphragm has two different surfaces; it is not bi-directional. It will fail if installed backwards! Roll the diaphragm so that the smooth surface (the pressure side) conforms to the inside of the push rod chamber cover and reassemble the six retaining screws (#6, Fig. or #9, Fig. ) with an installation torque of 5 foot-pounds. Set up the Model DDX Deluge Valve as per the section Resetting Model DDX Deluge Valve Systems. CONDITION TWO (System Air coming out of the bleed hole): System air coming out of the bleed hole is caused by a defective O-ring assembled to the push rod guide (#, Fig. or #, Fig. ). Remove the piston-push rod subassembly, push rod spring (#4, Fig. or #, Fig. ), and push rod guide (#, Fig. or #, Fig. ). Verify by hand turning, that the push rod cannot be unscrewed from the piston. Replace all O-rings and the push rod guide (#, # and #, Fig. or #9, # and #, Fig.). The correct installation torque for the pushrod guide is 5 inch-pounds. CAUTION: Do not over tighten the push rod guide. Reassemble the components that were initially removed. Re-install the diaphragm (#8, Fig. or #4, Fig. ) if it appears to be in good shape, otherwise, replace it also. NOTE: The diaphragm has two different surfaces; it is not bidirectional. It will fail if installed backwards! Roll the diaphragm so that the smooth surface (the pressure side) conforms to the inside of the push rod chamber cover and reassemble the six retaining screws (#6, Fig. or #9, Fig. ) with an installation torque of 5 foot-pounds. Set up the Model DDX Deluge Valve as per the section Resetting Model DDX Deluge Valve Systems. 0.

SOLENOID VALVE INSPECTIONS, TESTS AND MAINTENANCE WARNING: THE OWNER IS RESPONSIBLE FOR MAINTAINING THE FIRE PROTECTION SYSTEM IN PROPER OPERATING CONDITION. ANY SYSTEM MAINTENANCE OR TESTING THAT INVOLVES PLACING A CON- TROL VALVE OR DETECTION SYSTEM OUT OF SERVICE MAY ELIMINATE THE FIRE PROTECTION OF THAT SYSTEM. PRIOR TO PROCEEDING, NOTIFY ALL AUTHORITIES HAVING JURISDICTION. CONSIDERATION SHOULD BE GIVEN TO EMPLOYMENT OF A FIRE PATROL IN THE AFFECTED AREA. WARNING: PRIOR TO OPERATING THE SOLENOID VALVE, BE SURE TO CLOSE THE SYSTEM CONTROL VALVE TO AVOID UNINTENTIONAL OPERATION OF THE DELUGE VALVE. Inspections: It is imperative that the system be inspected and tested in accordance with NFPA 5 on a regular basis. The frequency of the inspections may vary due to contaminated water supplies, corrosive water supplies, or corrosive atmospheres. In addition, the alarm devices, detection systems, or other connected trim may require a more frequent schedule. Refer to the system description and applicable codes for minimum requirements.. The valve must be inspected at least monthly for cracks, corrosion, leakage, etc., and cleaned, repaired, or replaced, or replaced as necessary.. If Leakage is suspected through the solenoid valve, the valve diaphragms and seat should be inspected and if necessary, repaired or replaced. WARNING: CLOSE SYSTEM CONTROL VALVE, TURN OFF POWER SUPPLY, AND DEPRESSURIZE VALVE BEFORE DISASSEMBLING VALVE. IT IS NOT NECESSARY TO REMOVE THE VALVE FROM THE PIPE LINE TO MAKE INSPECTIONS. 4. When lubricating valve components, use high grade silicone grease (Dow Corning Compound Lubricant or equal). 5. When reassembling, tighten parts to torque values indicated in the manufacturer s maintenance instructions (packed with valve). 6. After maintenance is completed, operate the valve a few times to be sure of proper operation. A metallic click signifies the solenoid is operating. 7. All service must be performed by qualified personnel. Upon completion of inspections or replacement of the valve, the entire system must be checked for proper operation.
