Forged Piston Check Valve

We are a trusted supplier in China, specializing in the production of forged piston check valves that adhere to API 602 and ASME B16.34 standards. Our comprehensive range covers sizes from 1/2 to 3 inches, catering to Class 150-4500 LB specifications. Crafted from high-quality materials such as forged carbon steel, stainless steel, and alloy steel, our forged piston check valves are designed to provide reliable performance across various applications.

Forged steel check valve is to rely on the flow of the medium itself and automatically open and close the valve disc, used to prevent the reverse flow of medium, also known as check valve, one-way valve, reverse flow valve, and back pressure valve.  The body guide ensures alignment of the seat and disc when the piston check valve closes, the flow pressure will force the disc to lift off the seat and allow fluid to pass through the valve
