Sliding ball type check valves's disc is a rubber ball. The ball 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's. It can be installed vertically or horizontally and widely used in cold water, hot water, Industrial water and sewage's pipeline and it is more for sewage submersible pump.

1.Noiseless.
2.The rubber ball disc is totally encapsulated in EPDM rubber for superior sealing and corrosion resistance.
3.The rubber ball disc rises above the flow profile reducing possible wear and damage.
4.Simple design, top entry cover allows for access for cleaning, replacement and maintenance easy.
5.Much shorter stroke to minimize water hammer and water slamming.
