100 years of the KLINGER piston valve
The KLINGER piston valve - unique & sold millions of times is celebrating a big anniversary!
In the year 1922 – precisely 100 years ago – Richard Klinger constructed the first valve with an elastic, exchangeable sealing system for higher temperature ranges: the KLINGER piston valve. From 1923 onwards, KLINGER also manufactured shutoff valves with cylindrical pistons as shutoff elements and exchangeable valve ring packages. Over the course of time, the sealing materials have been adapted to the corresponding, applicable industry standards. The tried and proven principle of operation of the sealing system, however, is still the same standard employed today.
The KLINGER piston valve marked the invention of the classic industrial valve and laid the foundation for the pioneering role in piston valve technology.
Controlling and managing media flows
This is how the encompassing field of a globally active specialist is best characterized.
The KLINGER piston valve, with the elastic sealing system, is the special-purpose valve for the highest demands in terms of tightness. The piston valve (KVN) is also able to effortlessly score with the in-line service, i.e. maintenance in the installed state.
The impressive technology
The sealing system is created by a stainless steel piston, which is enclosed by two elastic valve rings. The upper valve ring ensures tightness to atmosphere while the lower one reliably provides sealing in the bore. The large sealing surface of the valve rings thus results in optimal sealing. In order to allow for easy actuation even in the event of high differential pressure, the pistons of the series KVN VIII, DN 65 to 200, are executed in a pressure-balanced manner. When closing the valve the piston pushes contaminants that may be present in the medium away from the inner side of the lower valve ring. As a consequence even contaminated media can be reliably sealed off and damage to the sealing surface negated.
Development over the decades
Across 100 years the piston valve has always presented itself as the state of the art, and by means of continuous development, in different designs and variations.
The KLINGER piston valve leaves no questions unanswered in terms of its areas of application. No matter whether a “Fire Safe”, an “Oxygen version”, or a valve in accordance with the German “TA-Luft” is required – numerous inspections and certificates underline the operational safety and guaranteed tightness.
Today the product is used around the globe a million times over, with various connection types (flange, threaded, butt and socket weld ends) and in different designs.
