Main features: The three eccentric butterfly valve rotates the positive cone angle by one angle to a diagonal cone angle, which reduces the eccentricity between the valve stem and the valve body center, and the opening torque also decreases accordingly. Widely used in industrial pipelines such as metallurgy, power, petrochemicals, as well as water supply and drainage and municipal construction, for regulating flow and carrying fluids.
