Bermad FP 400E-3M Electro-Pneumatically Controlled Deluge Valve
The Bermad Model FP 400E-3M Classic Deluge Valve includes a Manual EasyLock Reset for latching the valve open in response to an electric, hydraulic, pneumatic, or electro-pneumatic signal. The Deluge Valve resets to the closed position only upon local manual reset activation.
Operation
The BERMAD Model FP 400E-3M is suitable for systems that include electric fire detection and a piping system with a wide variety of open nozzles. Being electro-pneumatically controlled, the Model FP 400E-3M is recommended in cases, such as seawater installations, where it is advantageous to keep the solenoid dry. In the SET position, the line-pressure supplied to the main valve’s control chamber via the priming line and through an EasyLock Manual Reset, is trapped by the EasyLock internal check valve, by a closed Pneumatic Pressure Operated Relief Valve (PORV), and 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 PORV is held closed by the maintained pneumatic pressure, supplied through the Solenoid.
Under FIRE or TEST conditions, an electric detection system, through a control panel, triggers the Solenoid to release the trapped pneumatic pressure from the PORV, thereby opening it. Pressure is then released from the control
chamber through the opened PORV, 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.
