The ZSFM300-16DEP-F diaphragm deluge alarm valve is specially designed for ultra-large fire fighting scenes. The large DN300 diameter is suitable for high-pressure systems. A single valve can cover an area of 4,500 square meters and is suitable for inflammable and explosive and large-area fire protection in petrochemical, electric power, transportation and other industries. Full coverage of high-pressure water flow is achieved through large-flow channels to meet the fire extinguishing efficiency requirements in high-risk places. The valve body is made of high-strength ductile iron, with a temperature-resistant diaphragm and stainless steel springs, which is corrosion-resistant and can withstand high-pressure shocks. The explosion-proof design has passed dual certification and supports multiple starting methods such as electric and manual. The built-in anti-misoperation device ensures continuous water supply. The modular structure is easy to maintain, key components are quickly replaced, and it is suitable for foam combination systems. It is widely used in ultra-large storage tank areas, chemical parks, etc., providing reliable fire safety protection for extreme environments.
