Dual Plate Check Valve

Huachao Dual Plate Wafer Check Valve has One Piece cast heavy stronger Body configuration provides reduced weight and size compare to a swing check valve or lift check valve. This results in saving Initial cost, space and pipe support element installation. 

The Dual Plate, Wafer Check Valve employs two-spring-loaded plates hinged on a central hinge pin. When the flow decreases, the plates close by the action of torsion spring before flow reversal takes place. All features put together make the Dual Plate Check Valve as the most efficient & versatile design. It is also referred to as SILENT CHECK VALVE
