Dual Disc Wafer Flanged Swing Check Valve

Dual-Disc Wafer Type Check Valve 900LB  

Wafter check valves are sleek and made to fit in tight spaces between two flanges. There are no controls on this valve. The main component of the valve is a swinging disc in the center that opens in one direction and closes if liquids flow back the other direction. we recommend Wafer Check Valves for applications where flow is not an issue, and swing check valves when a full port valve is required. 

DCV Series

1. Dual Plate, Swing typedisc
2. Two torsion springs are used excreting on each of the pair valve plates,which close the plates quickly and automatically.
3. The quick-close action prevents the medium from flowing back and eliminateswater-hammer effect.
4. This valve is short in length, so that it is rigid and easy to mount.
5. It is easy to install on pipeline which is laid horizontally or vertically.
6. This valve is tightly sealed without leakage under the pressure watertest.
7. Safe and reliable in operation, high interference-resistance.
8. The hinge pin of the valve should be perpendicular to the horizontallevel when the valve is mounted on horizontal pipeline, for vertical installationthe direction of flow should be downward.
 9.metal to metal seal or metal seal are both available.
10. Long Pattern type.

Application:

• Steel dual plate wafer swing check Valve is used for preventing the back-going of medium in pipelines and equipments, and the pressure of medium will bring the result of opening and closing automatically.When the medium is back-going, valve disc will automaticaly closed to avoid accidents
