Diaphragm valve FDV-PP series

pneumatically-operated

* 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 Dry Pilot Line’s pneumatic 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
