The dual plate check valve is an all-purpose non return valve.
It is much stronger, lighter in weight and smaller in size.
Working 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.
FlowValve Dual Disc Check Valves are available in Wafer Type, Lug Type, Flanged Type.
