Forged steel check valve is to rely on the flow of the medium itself and automatically open, close disc, used to prevent the medium backflow valve, also known as the check valve, check valve, reverse flow valve, and back pressure valve.
Product use: The oxygen special globe valve is made of silicon brass or stainless steel with excellent material, which has the advantages of high mechanical strength, wear resistance and good safety. Used in oxygen pipeline, it has the best explosion-proof and flame retardant performance, and eliminates the unsafe factors on oxygen pipeline.
Structure characteristics and use of steam pressure reducing valve: High sensitivity steam pressure reducing valve belongs to pilot piston pressure reducing valve. It consists of main valve and pilot valve. The main valve is mainly composed of valve seat, main valve disc, piston, spring and other parts.
