Swing Check Valve

At Flowlink Valves & Controls, our swing check valves are designed to prevent backflow in pipelines, making them ideal for horizontal or vertical fluid systems. These valves feature a disc that swings open with forward flow and closes when flow reverses. Made from stainless steel, carbon steel, and alloy, they handle a wide range of pressures and temperatures, while effectively preventing water hammer and reducing system strain. Suitable for industries such as oil & gas, petrochemical, and water treatment, our swing check valves meet API, ASME, and ISO standards for reliable performance and safety.
