API 602 Check Valve

303 products found

An API 602 check valve is a compact, high-pressure safety valve specifically engineered to meet the stringent design, dimensional, and testing criteria of the American Petroleum Institute for small-bore forged steel valves (typically 2 inches and smaller). Available in piston, swing, or ball check configurations with socket-weld, threaded, or flanged ends, these valves feature a robust forged carbon or alloy steel body that delivers superior grain structure and structural integrity under severe thermal cycling and pressures up to Class 1500 and higher. They operate automatically via line pressure to permit unidirectional flow and instantly seal tight against reverse flow, protecting small-diameter piping lines, pumps, and instrumentation systems. Your upstream and downstream operations demand check valves that never compromise. Our China check valve manufacturers' platform delivers API 602 check valves, precision-forged and rigorously tested for bubble-tight shutoff and extended service life, so you can run your oil, gas, and petrochemical process lines with complete confidence.
