Swing check valves are designed to prevent reverse flow in pipelines by allowing fluid to flow in one direction only. The flanged swing check valve shown features a hinged disc mechanism that automatically opens with forward flow and closes when flow stops or reverses, ensuring reliable backflow protection.

This valve type is widely used in steam, water, oil, gas, and industrial utility systems, where protecting pumps, compressors, boilers, and process equipment from reverse flow is critical. The flanged end design provides strong mechanical connection, leak-free sealing, and easy integration into industrial piping networks.

Swing check valves operate automatically without manual intervention, making them ideal for continuous process operations.
