Product Type: Check Valve
Product Name:Diaphragm Type Check Valve
Place of Origin: China
The Diaphragm Type Water Hammer Preventive Check Valve comprises valve body, disc and guide chamber.
The valve body is made of ggg50 ductile iron, which provides strength and durability. The EPDM rubber
encapsulated disc with the strengthening nylon ensures maximum corrosion resistance and drop tight seal.
The special streamline design of the guide chamber gives low resistance.
Quick opening and closing with no mechanical impact allows the valve work noiselessly. The valve disc can
effectively absorb water hammer in the pipe, thereby reducing vibration. The valve is simple, light weight, and
Application: The valve can be used in potable water distribution system, sewage water treatment plants,
petrochemical industry, energy and power system, food and pharmaceutical industry, natural gas and coal
gas system, HVAC system, fire control system and construction building pipelines, to prevent the reverse of flow.
