The 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 design is the result of attempts to solve the problems associated with swing check valve and lift check valve. The Dual Plate Check Valve employs two spring-loaded plates 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. It is also referred as SILENT CHECK VALVE.
