Double Eccentric Butterfly Valves

Features

Double eccentric butterfly valves are the quarter turn disk valves with significant decrease of fact-to-face dimension, minimal contact between disc and seat during the operation and provides stable sealing performance with less wear of the seats over a long period of life time.

Double eccentric butterfly valves also known as high performance butterfly valves are ideal solution for low and mid pressure applications, gases, low viscosity and density liquids. The compact design along with quarter-turn operation provides a significant ease of operation and maintenance.
