Ductile Iron Soft Seated Gate valve Flange End DN50-DN800

Soft Seated Gate Valve Flange End DN50-DN800

1.PRODUCT PROFILE

Soft seated gate valves, in ductile iron with flat body and EPDM covered wedge.Traditional gate valves often have water leakage and corrosion. In order to overcome this shortcoming, the soft seated gate valve appeared. As an updated product of the traditional gate valve, the soft seated gate valve overcomes the shortcomings of poor sealing performance, poor elasticity, and easy corrosion of general gate valves.
The soft seated gate valve uses a flexible rubber-wrapped gate, which uses the elastic energy of rubber to produce a small amount of deformation compensation, so that the valve can achieve a good sealing effect.
