KONRAD technology: Double eccentric design

The permanent sealing of KONRAD Armaturen is achieved by the low-friction swinging of the valve disc into the conical housing seat. This requires a double eccentric arrangement of the valve disc, whose axis of rotation lies both outside the sealing level and the centre of the housing.

This geometry achieves optimum sealing behaviour with simultaneously low actuating forces. The minimised mechanical stress ensures low wear and thus offers you a long service life of the seal.

In contrast to the centric design, this construction allows the use of a wide range of seal materials, so that the use for a wide variety of media is possible, even under high temperatures and pressures.

Centric design

First eccentricity

The seat is axially offset from the shaft.

Second eccentricity

The shaft is offset from the centre of the housing.
