Features:

API check valves are designed for high-pressure applications and workover equipment, with working pressures ranging from 10000psi(70MPa) to 15000psi(105MPa). These valves are available in sizes ranging from 2" to 3" and are installed in high-pressure pipelines to prevent fluid from flowing back. When fluid is pushed back, a retainer plate automatically closes the valve.

These check valves are forged from high-strength alloy steel using US technologies and come with unions on both ends for easy dismantling. The retainer plate inside the valve is sulfidized with Buna-N for a good sealing effect and a longer service life under high pressure, suitable for both conventional and H2S environments.
