Lug Check Valve

The Dual Plate Check Valve design is the result of attempts to solve the problems associated with 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 torsion spring action without requiring reverse flow. This design offers the twin advantages of No Water Hammer and Non Slam simultaneously. All features put together make the Dual Plate Check Valve one of the most efficient design. It is also referred as SILEN T CHECK VALVE.

» Maximize the flow path area throught the valve with a lowwer pressure drop

» With no drilling throught the body wall, valve is intrinsically fire safe

» Lower pressure drop and increased Cv for valves NPS 24 (DN600) and larger

» Use shock bumpers on the baack of each disc 

» No holes throught the body wall, so leakage to the outside is impossible, and therefore emission-free

» As the FlexCheck has only one moving part and no bearings
