Dual Plate Check Valve
The dual plate check valve is an all purpose non return valve that is very durable, lighter in weight and smaller in comparison to a conventional swing check valve or lift check valve.
The dual plate check valve design is the outcome of attempts to overcome the problems that are related with conventional 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 the action of torsion spring before flow reversal takes place. This design offers the dual advantages of no water hammer and non slam simultaneously. With these features Dual Plate Check Valve becomes the most efficient & versatile design. It is also referred to as Silent Check Valve.
