ZDRO series electric 0-type cut-off ball valves consist of electric actuators and 0-type ball valves. DN15-200 is floating ball type and DN250-300 is fixed ball type.

The valve is compact in structure, small in volume, light in weight, convenient in assembling, disassembling and repairing, open in runner, small in flow resistance and good in sealing performance. The valve seat adopts flexible lip structure, which has the function of wear compensation and automatic pressure relief in the middle chamber. Therefore, the seal is reliable and the service life is long.

It is widely used in petroleum, chemical industry, electric power, metallurgy, steel, paper-making, medicine, food, textile, light industry and other industries.
