Check valve creates the metal-to-metal seal by the pressure of the medium, the more the pressure is, the better the sealing effect is. Anytime the valve chamber can bear the pressure of the pipeline. The sealing face between valve core and valve body is welded with hard alloy with good abrasion resistance and anti-scour, the valve core is made of sulfide-resistance steel and the others adopts the process of hardness limit so the valve is able to be used in H2S condition.
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.
