DN 150 - 1000 (KHSVI VVS up to DN 800)
Excellent thermal resistance, a long service life and a performance that ensures efficiency. These mission-critical characteristics can be found in all our products and solutions for district heating applications.
KLINGER Fluid Control products meet international standards and quality specifications. This in combination with the unique sealing system feature of for example the Ballostar KHI range provides extra safety and efficiency. A 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.

Total Cost of Ownership
KLINGER Fluid Control ball valves guarantee a perfect combination between technical performance and economic advantage. Initial costs, service-related costs, explicit and hidden costs that are incurred during the entire operating life of the valve are to be considered.
KLINGER Ballostar KHSVI VVS ball valves, DN 150 to 800, have been successfully tested and certified by the TÜV Austria on the company-own multi-function test stand under inclusion of the expanded requirements of EN 488:2019.
Unique elastic sealing system
The ball valve can be pressurized in both flow directions. The elasticity of the sealing elements allows for a compensation of thermal expansions.
Thanks to this function, two primary sealed areas are constantly present in the bore.
Double Block & Bleed
Key benefit of this feature is that Ballostar KHI can be leak-tested at any time without having to open the pipeline.
