The main structural features of the 815 and 830 series American standard butterfly valves are clamp type and flange type three eccentric structures, while the main structural feature of the 815 and 830L series butterfly valves is that the valve body has a convex periphery and is designed as a single flange structure with screw holes. The 815 and 830 series butterfly valves are widely used in petroleum, chemical and industrial environmental water treatment, high-rise buildings, water supply and drainage pipelines. Its characteristics are:
Due to the use of a three eccentric structure, the sealing performance is reliable, ensuring that the butterfly plate does not contact the sealing seat when opening, 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.
The American standard butterfly valve adopts the standard
