Ballostar KHI Ball Valve
Decades of reliability guaranteed
KLINGER Ballostar® KHI ball valves are designed to meet increasingly stringent requirements relating to tensile, compressive and bending stresses, while anticipating future standards.
Another distinctive feature of the Ballostar® KHI is its unique sealing system. A test and drain valve welded to the ball valve housing allows pressure to be relieved intermediately while the ball remains closed.
This enables the Ballostar® KHI to be leak-tested at any time without having to open the pipeline.
These ball valves are suitable for a wide range of applications, including underground district heating trenches, buried pipelines, co-generation power stations, pump stations, steelworks, hydroelectric power stations and tunnel boring machines.
