Deluge alarm valve zsfg deluge valve

The Deluge Alarm Valve ZSFG is a hydraulically operated, pilot-controlled valve designed for fire suppression systems requiring rapid, full-flow water discharge. It is available in nominal diameters of DN100, DN150, and DN200, with a rated working pressure of 1.2 MPa. The valve undergoes a seal test at 2.4 MPa and a strength test at 4.8 MPa, ensuring structural integrity under extreme hydraulic stress. These values are measured under standard industrial test conditions and reflect the valve’s performance limits, not operational defaults.

The valve body is typically constructed from ductile iron or bronze, with internal components including a diaphragm, pilot valve, and check valve made from corrosion-resistant materials. These materials align with standard fire protection industry practices for wet-pipe deluge systems. The valve does not include integrated electrical components; activation requires an external detection system. It is designed for use in environments where water supply pressure is stable and sufficient to maintain the pilot system.

This valve is commonly specified in high-hazard industrial facilities, aircraft hangars, chemical storage areas, and large-scale warehouse fire protection systems. Buyers include fire engineering contractors, facility managers in manufacturing, and safety compliance officers. Trade terms are typically FOB Qingdao, with packaging in wooden crates. Lead time and minimum order quantity are not stated and must be confirmed directly with the supplier. Installation requires compliance with NFPA 13 or equivalent local fire codes.
