Intelligent electric valve is composed of intelligent electric actuator and valve body composition by direct casting, precision of U shaped elastic sealing ring and the three eccentric multi-level metal seal structure, widely used in medium temperature ≤ 425 ℃ metallurgy, electric power, petrochemical, and water supply and drainage and municipal construction and other industrial pipelines, intelligent electric butterfly valve flow capacity, the normal temperature, clean medium, can choose the valve plate with soft seal (rubber ring, PTFE ring) to reduce leakage (up to zero leakage), high temperature and high pressure conditions can choose three eccentric hard seal valve for regulating the flow of fluid and set off with. Intelligent electric valve seat and disc sealing surface and are made of stainless steel with different hardness, good corrosion resistance, long service life, intelligent electric valve has two-way sealing function, the products comply with the national standard GB/T13927-92 valve pressure test.
