The Use and Features of Ball Check Valve

What is a Check Valve?

The check valve is also known as the counter valve, back pressure valve. This type of valve is automatically opened and closed by the force generated from the flow of the medium in the pipeline. It is a type of automatic valve. When a sanitary check valve is used in the pipeline system, its main role is to prevent media backflow and reversal of the pump and its driving motor and media discharge. The check valve can also be used in pipelines that supply the auxiliary system where the pressure may rise to the level above the pressure of the main system.

What is Ball Check Valve?

Ball check valves all use rubber balls as valve flaps. The mechanism is that under the influence of the medium, rubber balls can roll back and forth on the slide in the valve body to open or close the valve.

The Use and Features of Ball Check Valve

Single ball micro-resistance ball check valve HQ44X and double ball micro-resistance ball check valve HQ45X are characterized by large flow, small flow resistance loss, good sealing performance, muffled closing, the ability to reduce water shock.

They can be horizontally or vertically installed. Micro-resistance ball check valve can be used at the pump outlet of pipe networks such as cold water, hot water, industrial and domestic sewage to prevent media backflow. And in order to prevent media backflow, check valves should be installed on equipment, devices, and pipelines.

Conclusion

A ball check valve functions by means of a ball that moves up and down inside the valve. The seat is machined to fit the ball, and the chamber is conically shaped to guide the ball into the seat to seal and stop a reverse flow.
