The Double Eccentric Arrangement

Reliable sealing of Konrad valves is achieved by low-friction pivoting of the valve disc into the conical housing seat. This necessitates a double eccentric arrangement of the valve disc hose axis of rotation is outside the sealing axis and the tube axis. This geometry brings about an optimal sealing behaviour while keeping the actuating forces low. The minimized mechanical stress ensures low wear and tear and thus a long life of the seal.
