What's Double door wafer check valve ?

Double door wafer check valve  is an all purpose non return valve that is much stronger, lighter in weight and smaller in size compared to a conventional swing check valve or life check valve.

The Double door wafer check valve employs two spring-loaded plated hinged on a central hinge pin. When the flow decreases, the plates close by torsion spring action without requiring reverse flow.This design offers the twin advantages of No Water Hammer and Non Slam simultaneously. All features put together make the Dual Plate Check Valve one of the most efficient design. 

we have rubber seat dual plate check valve for low pressure and normal temperature,with wonderful sealing performance,and also the metal seat dual plate check valve for severe working conditions,high temperature,high pressure,hard working conditions.
