　　The cast steel swing check valves are manufactured according to API, ANSI, ASME standard, for industrial applications. The cast steel swing check valves are manufactured with bolted cover and renewable seats. Standard materials are A216WCB/F6, but other materials and other trims are available upon request.

　　A swing check valve or tilting disc check valve is check valve in which the disc, the movable part to block the flow, swings on a hinge or trunnion, either onto the seat to block reverse flow or off the seat to allow forward flow

　　A lift-check valve is a check valve in which the disc, can be lifted up off its seat by higher pressure of inlet or upstream fluid to allow flow to the outlet or downstream side. A guide keeps motion of the disc on a vertical line, so the valve can later reseat properly. When the pressure is no longer higher, gravity or higher downstream pressure will cause the disc to lower onto its seat, shutting the valve to stop reverse flow.
