The Reliable Model DDX Deluge Valve is a hydraulically operated, differential-type valve used to control the water supply to a deluge or preaction system. Deluge systems use open sprinklers or nozzles as discharge outlets in the fire area, while preaction systems use closed sprinklers or nozzles. Both systems use separate detection devices to control the operation of the Deluge Valve. Three simple trim arrangements allow for actuation of the Reliable Model DDX Deluge Valve by utilizing manual, hydraulic, pneumatic, or electrical devices. These devices include break glass stations, wet pilot sprinklers, dry pilot sprinklers, thermal detectors, and smoke detectors. The Reliable Model DDX Deluge Valve can be reset externally, without cover removal. This i s accomplished by pushing in and turning the external reset knob at the rear of the Deluge Valve (see Fig. 2).
Valve Operation The Reliable Model DDX Deluge Valve is shown in both closed and open positions in Fig. 3. In the closed position, the supply pressure acts on the underside of the clapper and also on the push rod through the push rod chambers 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 chambers 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 Valves 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.2). 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 Valves 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 6503050001, can be installed into the pushrod chambers releasing line to limit the pressure to 175 psi (12,1 bar). Reliable Model DDX Deluge Valves with associated trim sizes 4" (100 mm), 6" (150mm) and 165mm, are rated for use at a minimum water supply pressure of 20 psi (1,4 bar) and a maximum water supply pressure of 250 psi (17,2 bar). Water supplied to the inlet of the valve and to the push rod chamber must be maintained between 40F (4C) and 140F (60C). Detection and Actuation In general, the Reliable Model DDX Deluge Valve can be released by any Reliable UL Listed or FM Approved device that opens sufficiently to vent the push rod chamber in response to a fire. The releasing device is simply connected to the push rod chambers outlet. When the releasing device operates and vents the push rod chamber, the Deluge Valve opens. Typical releasing devices include hydraulic manual emergency stations, M odel F1-FTR Fixed Temperature Detectors on wet pilot lines, dry pilot actuators, and solenoid valves. Model F1-FTR Detectors perform both Deluge Valve releasing and fire detection functions with wet pilot lines. The use of a solenoid valve for Deluge Valve releasing enables various types of electrical fire detection devices to be used. Typical detection devices include electrical emergency pull stations, thermal detectors, and ionization or photoelectric smoke detectors. Electrical detection and releasing equipment used in Supertrol Electrical Systems is described in Bulletins 707 and 708, for both deluge and preaction systems.
