Brief introduction：
Sliding ball type check valves disc is a ball coated with rubber and dependant on the line pressure .The ball can slide up and down in the integrated chute in the body to open or close the valves without any noise and water-hammering and good sealing capability. The bore is full without any block so the flow rate is much with little resisting force and little pressure loss and water-head loss is 50% of swing check valves. It can be installed vertically or horizontally and widely used in cold water's, hot water's, industry's and sewage's pipeline and it is more for sewage submersible pump.
