Electric butterfly valve design is reasonable, easy assembly and disassembly, easy to repair, simple and compact structure, light weight, 90 ° rotation, opening and closing quickly. Eccentric structure of the electric butterfly valve to reduce the friction ring, to extend the service life of the valve. Sealing structure design is reasonable, to be completely sealed, zero leakage, to adapt to harsh working conditions. Replace the valve plate seals, "0" ring, disc, shaft and other materials, applicable to a variety of media and different temperatures. In particular, electric butterfly valve with stainless steel ring, both anti-corrosion and wear-resistant to make the scope of application more extensive. Electric hard sealing flange butterfly valve for water, steam, oil, air, gas and other different media. The main features of electric flanged butterfly valve are: Suitable temperature -20 ~ 425oC; Working pressure, wear resistance, long life, quick opening and closing time; D943H electric seal flange valve sealing performance , With automatic centering effect, a small amount of leakage;? F PTFE sealing temperature ≤ 160oC. ? Electric hard sealing flange butterfly valve has been widely used in beverage, pharmaceutical, petrochemical, food, chemical, power plants, steel mills, industrial environmental water treatment, high-rise building water supply and drainage pipelines and other pipelines for regulating the medium flow and opening and closing Use.
