Pre Insulated Dual Plate Check Valves


VALTREE Dual Plate Check Valve is a universal application non return valve that is much durable, lighter in weight and smaller in size compared to a conventional reflux valve or a swing check valve. The Dual Plate Check Valve is designed exceptionally to solve the problems associated with conventional swing check valve and lift check valve. The Dual Plate Check Valve has 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. All features put together make the Dual Plate Check Valve as the most efficient & versatile design. It is also referred to as Silent Check Valve globally.
