Diaphragm valve FDV-PH series

* 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 a Wet Pilot Line’s hydraulic pressure release due to its exposure to flame heat * 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
