Operation
The BERMAD Model PC2-FP-400E-2M 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 supplied to the main valve’s control chamber [1] via the priming line [2] and through an EasyLock Manual Reset [3], is trapped by the EasyLock internal check valve, by a closed 2-Way Solenoid Valve [4], and by a closed Manual Emergency Release [5]. The trapped pressure holds the main valve’s diaphragm and plug against the valve seat [6], sealing it drip-tight and keeping the system piping dry. Under FIRE or TEST conditions, an electric detection system [E], through a control panel [C], triggers the Solenoid Valve to open. Pressure is released from the control chamber by the opened Solenoid Valve, or the Manual Emergency Release. The EasyLock prevents line-pressure from entering the control chamber, allowing the main valve to latch open and water to flow into the system piping and to the alarm device.
Engineer Specifications
■ The 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 a removable cover for quick in-line service, enabling all necessary inspection and servicing.
■ The control trim materials shall consist of S.S.316 tubing and fittings, and plated brass accessories including local EasyLock Manual Reset, 2-way Solenoid Pilot Valve, Y strainer 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 Deluge Valve shall latch open in response to an electric signal. The valve shall reset to the closed position only upon local manual activation of the reset device.
