Imported triple eccentric butterfly valveThe main structural features are clamp type and flange triple eccentric structure, with protruding ears around the valve body designed as a single flange structure with screw holes. Butterfly valves are widely used in petroleum, chemical, industrial environment water treatment, high-rise buildings, water supply and drainage pipelines. The characteristics of the device are: due to the use of a three eccentric structure. The sealing performance is reliable, ensuring that the butterfly valve does not contact the sealing seat when opened, eliminating uneven load on the sealing seat, extending its service life, and ensuring reliable sealing performance. It has advantages such as high temperature resistance, wear resistance, and corrosion resistance.
