The Swing Check Valve is a widely used one-way valve, mainly designed to prevent fluid reverse flow in pipelines. Its working principle: fluid flow and pressure push the valve disc open. Once the fluid reverses direction, the valve disc closes by its own weight to stop backflow.
This WESDUN swing check valve is made of WCB cast steel, composed of valve body, valve disc and hinge. With simple construction, it is convenient for maintenance. It is suitable for liquid, gas, steam and various industrial working conditions.
▪ The valve adopts a streamlined flow path for low fluid resistance.
▪ The valve disc is actuated by the medium to stop reverse fluid flow.
▪ The disc of the swing check valve operates without a guide in full open and full close positions. Multiple disc and seat configurations are available for different working conditions.
▪ The swing check valve delivers full unobstructed flow and automatically closes as pressure falls. It fully closes at zero flow to prevent backflow.
▪ Compact structure, small size and light weight, simple maintenance.
▪ The swing check valve achieves tight sealing with zero leakage during hydrostatic pressure test. It runs safely and reliably and has strong anti-interference capability.
