Butterfly Check Valve
Butterfly check valve are widely used in water, waste water and sea water. According to the medium and temperature, we can choose different material. Such as CI, DI, WCB, SS304, SS316, 2205, 2507, Bronze, Aluminium. The micro-resistance slow-closing check valve not only prevents the back flow of media, but also effectively limits destructive water hammer and ensures the safety of pipeline use.

Ductile Cast Iron Rubber Flap Check Valve
Rubber flap check valve is mainly composed of valve body, valve cover and rubber disc. W e can choose cast iron or ductile iron for valve body and bonnet. The valve disc we usually ues steel+rubber coating. This valve is mainly suitable for the water supply and drainage system and can be installed at the water outlet of the water pump to prevent back flow and water hammer damage to the pump.
