Cast Iron Dual Plate Check Valve
Dual Plate Check valve is a purpose non return valve that is much stronger, lighter in weight and smaller in size as compared to conventional swing check valve or lift check valve. This design has distinct advantages over conventional swing 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.
