Product Description

Seeko is one of the leading China Forged Steel Check Valve manufacturers, welcome to inquiry Forged Steel Check Valve from our factory.


A swing check valve consists of a flap or disc which hangs down in the flow path. With flow in the forwards direction, the pressure of the fluid forces the disc to swing upwards, allowing flow through the valve. Reverse flow will cause the disc to shut against the seat and stop the fluid going back down the pipe. In the absence of flow, the weight of the flap is responsible for the closure of the valve.
