Double Eccentric
Double Eccentric
Double Eccentric Butterfly valves are operating by a circular body, by %100 tight sealing through quarter turn (90 degree) disc rotating around its own axis. Valve body and discs/flaps are designed to provide minimum resistance. The purpose of the first eccentric is as follows : the pressure on the rubber sealing ring is reduced, the abrasive effect is raised, and the continuous contact between the sealing ring and the body site is achieved. During opening of the valve, the rubber sealing ring is easily separated from the body seat with the help of the second eccentricity.
