Bermad Model FP400E 5D - Hydraulically Control On-Off Deluge Valve
The BERMAD Model FP 400E–5D is suitable for systems that include wet pilot lines with closed fusible plugs. Providing boosted local opening, it is recommended for systems with elevated fusible plugs. The valve is closed as long as the wet pilot line is pressurized. It opens in response to a hydraulic pressure drop in the wet pilot line.

The BERMAD Model FP 400E־5D is suitable for systems that include wet pilot lines with closed fusible plugs (thermal releases), and piping systems with a wide variety of open nozzles. The typical wet pilot line, is installed in the covered area and connected to the valve trim. Providing boosted local pressure release from its control chamber, the Model FP 400E־5D is recommended for systems with remote and/or elevated pilot line fusible plugs.
In the SET position line-pressure, which is supplied to both the main valve’s control chamber  and a Hydraulic Relay Valve (HRV-2)  by the priming line , through a Check Valve , an Accelerator  with priming restriction and the wet pilot line  restriction , is trapped by the Check Valve, by the closed HRV-2, by the closed wet pilot line and by a closed Manual Emergency Release . The trapped pressure holds the main valve’s diaphragm and plug against the valve seat , sealing it drip-tight and keeping the system piping dry. The HRV-2 is held closed by the pressure in the wet pilot line.
Under FIRE or TEST conditions, a pilot line hydraulic pressure drop opens the HRV-2 causing water to exit through the Accelerator faster than it can be supplied. Pressure is then released from the main valve’s control chamber through the opened HRV-2, or the Manual Emergency Release, allowing the main valve to fully open and water to flow into the system piping and to the alarm device (if mounted).
The On-Off deluge valve shall be a UL-Listed, hydraulically controlled, elastomeric type globe valve with a rolling-diaphragm.
The valve shall have an unobstructed flow path, with no stem guide or supporting ribs.
Valve actuation shall be accomplished by a fully peripherally supported, one-piece balanced rolling-diaphragm, vulcanized with a rugged radial seal disk. The diaphragm assembly shall be the only moving part.
The valve shall have removable cover for quick in-line service enabling all necessary inspection and servicing.
The control trim materials shall be S.S.316 tubing and fittings and plated brass accessories, including Y strainer, Accelerator, Hydraulic Relay Valve (HRV-2), and Manual Emergency Release.
The control trim shall be supplied as an assembly, pre-assembled and hydraulically tested at an ISO 9000 and 9001 certified factory.
The Hydraulically Controlled, On-Off Deluge Valve shall fully open in response to a wet pilot line hydraulic pressure drop.
