Diaphragm valve FDV-PE series

electrically-actuatedcontrolpressure-reducing

* Hydro-dynamic pattern design ensures high flowrates with minimum head loss * The valve trips open automatically upon a gradual release of water pressure from its control chamber. The valve is actuated by an electric signal transmitted to the valve’s solenoid from the main control valve panel, due to a flame heat exposure of heat detection sensors system * Soft closing upon pressurization of the valve’s control chamber, by line pressure or other independent water source, prevents surges * A pressure reducing pilot enables a full control over the downstream pressure and ensures a steady set in a wide pressure range The FDV-PE1 resets to stand-by close position by de-energizing the alarm system solenoid’s coil through the main control panel
