Swing check valve

Swing check valve is one kind of one-way check valve to effectively prevent water stop and backflow. Because of its unique design structure, it will not affect the service life of the pump, so the swing check valve is also called "large diameter whole basin" check valve. It is the preferred general valve in fire fighting pipe network and municipal pipe network.

Swing check valve is made of ductile iron material, tensile resistance, crack resistance and other advantages, the sealing surface has brass welding or EPDM rubber seal two sealing forms. Suitable for different occasions in the pipe network, the valve body is coated with epoxy resin to ensure that the water quality and service life are affected by fluid corrosion. The valve plate guide shaft adopts 304 stainless steel to effectively prevent the rotation failure caused by fluid corrosion, which cannot be normally opened or closed, causing damage or damage to the water pump and other facilities, resulting in unexpected secondary serious problems.
