Klinger Piston Valves
Klinger: A Success Story
1893, Richard Klinger founded the Klinger group and opened its first
manufacturing plant near Vienna, Austria. Klinger's early inventions
included the reflex level gauge and compressed sheet gasket materials.
In 1922, Richard Klinger invented the piston valve by replacing the
disk and seat of a conventional globe valve with a cylindrical piston
and two resilient, replaceable sealing rings. Constant research
and development have resulted in sealing rings that provide the piston
valve with an extraordinary ability to seal line pressure and prevent
leakage to the atmosphere.
Independent testing laboratories have subjected Klinger piston valves
to API fire tests and Helium leak tests. The Klinger piston valve
has out-performed other generic valve types in these tests; and these
results have been consistently confirmed by extraordinary performance in
Over 60 millions Klinger piston valves are in service worldwide.
