Model ZSFM Deluge Alarm Valve
The deluge alarm valve ZSFM is the main regulating element of the deluge automatic fire extinguishing system; it operates on the principle of a diaphragm check valve. The diaphragm assembly separates the upper and lower cavities of the valve. In standby mode, the pressure on both sides of the membrane is equalized, the membrane is pressed tightly against the seat, the valve is hermetically closed and blocks the flow of water into the system main.

Product Description
The deluge alarm valve ZSFM is the main regulating element of the deluge automatic fire extinguishing system; it operates on the principle of a diaphragm check valve. The diaphragm assembly separates the upper and lower cavities of the valve. In standby mode, the pressure on both sides of the membrane is equalized, the membrane is tightly pressed to the seat, the valve is hermetically closed and blocks the flow of water into the system main. If a fire occurs and a complex signal is received, the pressure on the sides of the membrane is disrupted; when the pressure from the water supply side exceeds the pressure in the pipeline, the membrane automatically opens, water intensively flows into the protected network for mass irrigation and fire extinguishing.
This one-way control valve is equipped with fire sensors, pressure switches, hydraulic bells and other components to form deluge systems of different sizes. Stable operation, fast response, high safety and reliability, wide range of applications. Used in automatic fire extinguishing projects for large facilities: hospitals, hotels, shopping centers, industrial workshops, airports, entertainment complexes, libraries, sports arches and exhibition centers, it is a key equipment for fire protection of large spaces.
