ZSFM80-16DEP-F diaphragm deluge alarm valve is a core device designed for high-risk firefighting scenarios. It adopts explosion-proof structure and large flow design. It is specially developed to meet the needs of flammable and explosive areas and large-area firefighting in industries such as petrochemical, electric power, and transportation. Its core function is to achieve rapid response by controlling the change of chamber pressure. When the fire signal is triggered, the valve opens quickly and instantly releases high-pressure water flow covering an area of 2,000 square meters, meeting the fire extinguishing requirements of NFPA 13 standards for high-risk places.
