PN 16/25/40
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.
The KLINGER Fluid Control ball valve range for the district heating sector not only keeps up with strict requirements but also assures to meet future standards with regard to tensile, compressive and bending stress. KFC ball valves reduce operating and maintenance costs and allow for a very long lifespan, providing a perfect TCO (Total Cost of Ownership) ratio.
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.

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.
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.
Key benefit of this feature is that Ballostar KHI can be leak-tested at any time without having to open the pipeline.
KLINGER Fluid Control offers a large selection of different designs and executions. All of the standard ball valves are EN488:2019 certified. Shut off ball valves can be equipped with manual gears and either electric, pneumatic or hydraulic actuators, different stem extensions and either a drain and/or a vent valve. In our standard portfolio insulated fittings are not included. Per request an individual tailor made solution can be worked out and made to order. We are proud to deliver various tailor-made solutions fitted for the high standards of special district heating requirements.
