DUAL PLATE CHECK VALVE

Design Features

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 lift check valve.

The Dual Plate Check Valve design is the outcome of attempts to solve the problems associated 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 twin advantages of No Water Hammer and Non Slam simultaneously.

The Valve design conforms to API 594 as well as API 6D except face-to-face dimensions of ANSI 125 Cast Iron valves of sizes 50mm (2”) to 300mm (12”). Dual Plate Check Valves are available in Wafer design, Soft Seating are available. Soft Seats are integrally moulded type.

Dual Plate Check Valves are used for applications like Water supply systems, Fire Water systems, Cooling Water, Chilled/Hot Water systems, Boiler Feed Water, Sea Water, Potable Water, Raw Water etc.
