Operation
The BERMAD Model FP 400E-3D is suitable for systems that include electric fire detection and a piping system with a wide variety of open nozzles.
In the SET position, the line-pressure, which is supplied to both the main valve’s control chamber [1] and a Hydraulic Relay Valve (HRV-2) [2], through the priming line [3], a Check Valve [4], an Accelerator [5] with priming restriction and a 3-Way Solenoid [6], is trapped by the Check Valve, by the closed HRV-2, and by a closed Manual Emergency Release [7]. The trapped pressure holds the main valve’s diaphragm and plug against the valve seat [8], sealing it drip-tight and keeping the system piping dry. The HRV-2 is held closed by the line-pressure through the solenoid.
Under FIRE or TEST conditions, an electric detection system working through a control panel, triggers the solenoid to open the HRV-2, causing water to exit through the Accelerator faster than it can be supplied. Pressure is then released from the main valve control chamber by the opened HRV-2 or the Manual Emergency Release, allowing the main valve to 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, electrically 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, 3-Way Solenoid, 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 Electrically Controlled, On-Off Deluge Valve shall open in response to an electric signal.
