Forged Steel Swing Check Valve
Product Details
Welded flange swing check valve the purpose of this type of valve is to allow the medium to flow in only one direction and to prevent the flow in that direction.Usually this valve is automatic work,in one direction of the flow of fluid pressure under the action of the disc open;When the fluid flows in the opposite direction,the fluid pressure and the self-coincidence of the valve disc act on the valve seat,thus cutting off the flow.
Working Principle
When the fluid flows in the correct direction, the pressure pushes the disc open, allowing smooth passage through the valve. Once the flow stops or reverses, the disc automatically swings back to the seat, closing the valve and preventing reverse flow without the need for external control.
