Wafer Dual Plate Check Valve H76H API594 CL150/300 Ductile iron disc spring load

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 

It is much easier to install between standard gaskets and line flanges, and therefore is more cost effective to install and to maintain. 

Its design complies with API 594 and API 6D, testing to API 598.
