Dual Plate Check Valves are automatic in operation and designed to prevent reversal of flow in fluid piping systems. These valves are maintained open by the flow of fluid in the straight direction and are closed by back pressure of the fluid.The swing check variation is a low pressure drop unit based on a hinged disc. This valve is suitable for low velocity applications with infrequent velocity reversals. The valve can be fitted with external weights to allow faster closure to reduce water hammer or shock pressure on flow reversal.
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 together. All the features put together make Dual Plate Check Valve as the most efficient & versatile design. It is also referred to as SILENT CHECK VALVE.Specifications:
