Dual Plate Check Valve, Size 50MM TO 600MM, Shape WAFER TYPE, Design Std API594

The inherent design of the twin plate backflow preventer valve results in significantly reduced weight when compared to conventional full, Bodied hinged check valves. As valves increase in size the dual plate check valves have the potential to be as little as one fifth the mass of the equivalent full, Bodied unit. Space and pipe support, This results, Savings in initial cost element installation. Hi, Tech dual plate check valves use an internal retention method which does not encroach on the gasket sealing surface. Other retainer, Less designs have an internal retention method incorporating a special key and retaining screws. These components encroach on the serrated sealing face area restricting the sort of gasket that is Appropriate for the screws, Use. Furthermore can corrode making maintenance difficult. Dual plate check valves are developed such that the discs are hinged at their sides like eliminating the, A door effect of gravity. Consequently, Very little energy is needed to open the valve and maintain resulting in, This position lower energy costs. The essence of each valve is the seat/seal interface. Hi, Tech valves are crafted with the use one of the top updated machining methods and equipment to achieve maximum flatness with a fine lapped finish. The end result is valves that easily meet and exceed test requirements of api 598 for metal, Seated check valves. For potentially severe applications, A high torsion spring ensures the valve closes with utmost speed possible.
