What is Metal Seat Dual Plate Check Valve ?

Metal Seat Dual Plate 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 Dual Plate 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.
