Check Valve

FEATURE

Check Valve is an automatic valve that prevents backflow of fluid, typically operated by pressure changes or gravity. Swing Check Valve is installed in horizontal pipelines, with the disc moving vertically for quick opening and closing, and is also effective for pressure maintenance.
