1.Check valves are mainly used for high pressure applications and workover equipment.
2.Sizes range from 2" to 3". The model of check valve available: D×F70-2"×2",D×F105-2"×2",D×F70-3"×3",D×F105-3"×3"
3.They are usually installed in high pressure pipelines for preventing fluid flowing back. When fluid is pushed back, a retainer
plate will automatically close.
4.Check valves, forged of high strength alloy steel based on US technologies, are fitted with unions on both ends for easy
dismantlement. The retainer plate inside sulfidized with Buna-N has a good sealing effect and a longer service life under high
pressure, for conventional or H S environments.
