HH47X(HH47H) title disc swing check valve with hammer balance and hydraulic
Slanting Check Valves are used on the outlet of the water pump of industrial water supply and sludge
treatment plant to prevent the medium inside the pipe network from going back, and remove
automatically the destructive water hammer so as to ensure both pump and pipeline not to get
damaged.
It consists of body, disc, buffer and micro-adjusting valve. And it features by the brand new structure,
small volume, small fluid resistance, reliable seal, wearable and good buffering performance.
It is really the best product for industrial use of water and city sludge drainage.
