overview
The ZDRO series electric 0-type cut-off ball valve consists of an electric actuator and a 0-type ball valve. DN15~200 is a floating ball type, and DN250~300 is a fixed ball type 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.
