Carbon Steel Swing Check Valve

While not a valve in the traditional sense, carbon steel swing check valves serve an important application-namely to prevent flow in one direction while allowing it in the other. A swing check valve is self-actuated and designed to prevent fluid from flowing back into the system (prevent reverse flow). Real-life applications include preventing backflow into an injection line or into a pump. The fluid flow opens the valve by forcing a disk or ball in one direction. When the flow stops, the disk or ball is seated and closes the valve. They can be installed in horizontal or vertical upward flow piping.

Bodies and covers are high quality cast and afterwards precisely machined, directing the attention to prevent stress concentration.

The design characteristic of swing check valve is the unobstructed passageway, with a full-opening when required.
