Forged Steel Flange Check Valve

Description:
The models of this kind of valve include H41H, H41Y, H41W, etc. The diameter range will be DN15-DN50 and the working pressure will be 900Lb-1500Lb. This check valve is made of forged steel. H41H, H41Y, H41W forged steel flange check valve can open and close automatically on the force from the flow of medium. This valve can also be called reflux valve, non-return valve, one-way valve or counterbalance valve. It is an automatic valve whose main functions are to prevent the backflow of medium, the reverse of pump and its driving and the leakage of the medium in the containers. This check valve can also be applied to the pipeline whose pressure may surpass the system pressure. This forged steel flange check valve can be divided into swing check valve and lift check valve. The swing check valve will rotate depend on the gravity. And the lift check valve will move along the axis.
