Other remarks 1 |
The sealing faces of valve seat and valve clack are build-up welded with hard alloy to improve the erosion resistance and extend the service life of valve. |
|
Other remarks 2 |
Short closing travel of valve clack, and small impact at valve closing; short structural length, most suitable for positions with limited mounting space |
|
Other remarks 3 |
Suitable for medium backflow prevention in pipeline or device |
|
Other remarks 4 |
Built-in pin roll, without external leakage point |
|
Other remarks 5 |
Due to loading of spring, the valve clack can move flexibly without jamming, and has a good sealing performance. |
Available retainer type and retainerless type
Independent spring design
A spring design of dual plate check valve(6” and larger) allows higher torque to be exerted against each plate with independent closing in response to the process stream.testing has proved this action provides about 20% improvement in valve life and 50% reduction in water hammer.Each of the dual plates has its own springs,which provide independent closing action
