PISTON VALVES

Piston valves stand for excellent industry performance with their minimum maintenance requirements and production savings.

KLINGER piston valves are characterised by a system of seals and rings that ensures tightness to atmosphere and thus prevents environmental contamination.

KLINGER has been at the forefront of piston valve technology since 1922. Featuring different types of connections – flanged, threaded, butt and socket weld ends – and both DIN and ANSI-compliant standards, KLINGER piston valves complete the wide range of KLINGER industrial valves.  

In addition to KLINGER piston valve range, our valves team can source and supply a range of other types of piston valves to suit client specifications.  Our team provides the technical know-how to recommend the best solution for the specific application and media. With experience across multiple industries including Oil and Gas, Mining, Chemical, Construction and more, clients are rest assured of gaining the best solution.  For more information about our valve packaged service offering visit our project management page.

KLINGER KVN piston valves leave no questions unanswered. Confirmed by a wide range of tests and certifications, plant operators can rely on absolute operational safety and a guaranteed tightness of seals.  KLINGER piston valves are ideal for control purposes.  For nominal sizes of DN 15 to 50, a regulating piston is utilized. A lantern bush is used for nominal sizes between 65 and 200.  The regulating piston and the lantern bush both feature a curved geometry, which results in a nearly linear flow line.  Thanks to the identical sealing system, the shut-off function is also guaranteed in the bore. Furthermore this design makes it possible to convert the KVN into a regulating valve at any given time by simply exchanging the piston or the lantern.
