Sliding ball type check valves disc is a ball coated with rubber and dependent 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 waters, hot waters, industry's and sewage pipeline and it is more for sewage submersible pump
