KLINGER piston valves are ideal to guaranteed the shut-off function in the bore thanks to the sealing system. The regulating piston and the lantern bush both feature a curved geometry, which results in a nearly linear flow line. 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.
