An API Swing Check Valve is a type of non-return valve designed to prevent backflow in piping systems. It complies with the American Petroleum Institute (API) standards, ensuring high performance in oil, gas, petrochemical, and other industrial applications.
Applications API Swing Check Valves are used in:
Oil & Gas – Pipeline systems, refineries, offshore platforms.
Petrochemical Plants – Chemical processing, high-pressure systems.
Water & Wastewater – Pump discharge lines, preventing backflow.
Power Plants – Boiler feed systems, cooling water lines.
Marine & Shipbuilding – Ballast systems, fuel lines.
Advantages
Low Pressure Drop – Minimal resistance to flow.
Self-Acting – No external power required.
Durable Construction – Available in carbon steel, stainless steel, alloy materials.
Disadvantages
Slower Response – Prone to water hammer in fast-reversing flows.
Horizontal Installation Required – Vertical installation needs a spring-assisted design.
