Triple Eccentric Butterfly Valves

Main features: The triple eccentric butterfly valve rotates the positive cone angle to an oblique cone angle, so that the eccentricity between the valve stem and the valve body is reduced, and the opening torque is also reduced. It is widely used in industrial pipelines such as metallurgy, electric power, petrochemicals, water supply and drainage, and municipal construction to adjust flow and cut off fluid.
