KLINGER BALLOSTAR KHI Ball Valve
Decades of reliability guaranteed with unique sealing mechanism
KLINGER Ballostar KHI ball valves are engineered to meet future criteria for tensile, compressive, and bending stress, ensuring compliance with evolving regulations. These valves feature a unique sealing mechanism, allowing pressure release when the ball is closed through integrated test and drain valves. Versatile applications include tunnel boring machines, underground district heating trenches, buried pipelines, cogeneration power plants, pump stations, steelworks, and hydroelectric power plants.
