Check valves are mainly used for high pressure applications and workover equipment. They are usually installed in high pressure pipelines for preventing fluid flowing back. When fluid is pushed back, a retainer plate will automatically close.

Check valves, forged of high strength alloy steel based on US technologies, are fitted with unions on both ends for easy dismantlement.
