API 600 Stainless Steel Swing Check Valve 15-300mm DN 1.0-10.0 MPa Non-Return Valve
Professional-grade non-return valve designed for industrial fluid control applications with pressure ratings from 1.0 to 10.0 MPa and diameters from 15mm to 300mm.
Swing check valves are automatic safety devices that allow fluid flow in one direction while preventing reverse flow. These valves feature a circular disc that rotates on a shaft, automatically closing when flow reverses to protect pumps, compressors, and piping systems from damage and water hammer.
