Non-return ball valves

More information

The great advantage of a non-return ball valve is its ability to handle dirty water. While other valves can start to leak if the water is dirty, the non-return ball valve is not adversely affected, thanks mainly to its self-cleaning operation. The non-return ball valve is robust and has a cast iron housing. It can be used for both horizontal and vertical applications.
