Check Valves

Our check valve is an automatic, low-maintenance valve designed to prevent reverse fluid flow in piping systems. It operates via fluid pressure without external power, featuring a compact structure, quick response, and tight sealing to avoid backflow damage. Available in multiple types and materials, it suits diverse working conditions for industrial and municipal use.
Specifications: Body Material: Cast iron, carbon steel (WCB), stainless steel (SS304/316); Type: Swing, lift, wafer; Size Range: DN15â??DN600 (1/2"â??24"); Pressure Rating: PN10â??PN40, Class 150â??300; Working Temp: -20â??â??425â?? (varies by material); Connection: Flanged, threaded (NPT/BSPT), welded; Sealing Material: EPDM, PTFE, metal-to-metal.

Applications: Widely used in oil & gas, petrochemical, power generation, water treatment, municipal water supply, and HVAC systems. Suitable for water, steam, oil, gas, and neutral/corrosive process fluids needing reverse flow protection.
