Electric cut-off ball valve
電動(dòng)切斷球閥Composed of an electric actuator and a 0-type ball valve, DN15~200 is a floating ball structure, while DN250~300 is a fixed ball structure. The valve has a compact structure, small volume, light weight, easy assembly, disassembly and maintenance, smooth flow channel, low flow resistance, and good sealing performance. The valve seat adopts a flexible lip structure, which has wear compensation and automatic pressure relief in the middle chamber, thus ensuring reliable sealing and long service life. Widely used in industries such as petroleum, chemical, power, metallurgy, steel, papermaking, pharmaceuticals, food, textiles, and light industry.
