KLINGER BALLOSTAR® KHI BALL VALVES
Decades of reliability guaranteed
KLINGER Ballostar® KHI ball valves will keep up with stricter requirements and are assured to already meet future standards with regard to tensile, compressive and bending stress. Its unique sealing system is another feature of Ballostar® KHI. The test and drain valve welded to the ball valve housing allows the pressure to be relieved intermediately while the ball is closed. The key benefit of this feature is that Ballostar® KHI can be leak-tested at any time without having to open the pipeline. These ball valves are fit for many different applications such as underground district heating trenches, buried pipelines, co-generation power stations, pump stations, steelworks, hydroelectric power stations and tunnel boring machines.
