Discover the centennial success of the KLINGER KVN piston valve: a reliable and cost-effective solution for industrial plants worldwide.
Richard Klinger’s piston valve invention laid the foundation for the valve industry and has made a significant contribution to the company’s success for 100 years. With millions of users worldwide, the KVN piston valve has become an indispensable part of industrial plants, providing minimal maintenance and cost savings.
The KVN piston valve scores with minimal maintenance and significant cost savings. Sophisticated technology makes this possible: the sealing element is formed by a stainless steel piston, which is enclosed by two elastic valve rings. The upper valve ring ensures tightness to the atmosphere, while the lower ring reliably provides sealing in the bore. The large sealing surface of the valve rings thus results in optimal sealing. The pistons of the KVN VIII series, DN 65 to 200, are produced with a pressure-balanced design in order to enable smooth operation even at high differential pressures. Upon closing of the valve, the piston pushes any impurities that may be in the medium from the inside of the lower valve ring. As a consequence, even contaminated media can be reliably sealed off, preventing damage to the sealing surface.
