Product Description:
ZAJO electric O-type cut-off ball valve (referred to as cut-off ball valve) is a rotary regulating valve, which is the execution unit in the electric unit combination instrument. Cutting off the flow path of the ball valve body has low resistance and high flow coefficient. The cylindrical through-hole ball valve core has shear function and can control viscous media with fibers and particles. The cut-off ball valve is equipped with a small, sturdy, and high-precision actuator that receives ON-OFF actions. It is sensitive to action and uses angle direct indication and feedback. It is widely used in gas, steam, and liquid transmission pipelines in production departments such as petroleum, chemical, papermaking, metallurgy, and sewage treatment to open and cut off media in order to achieve production processes according to certain specifications.
Product features:
Electric ball valve is a type of rotary ball valve with a rotation angle of 90 °. It has excellent sealing performance, high flow capacity, low flow resistance coefficient, simple structure, easy maintenance, and long service life. The valve body channel and connecting pipe diameter are equal and form one diameter, and the medium can flow through almost without loss. Equipped with DKJ-II, III actuators and high-performance actuators such as Japanese tooling and West German Omron. The product is usually used in occasions with strict sealing requirements. In addition to controlling gas, liquid, and steam media, it is also suitable for controlling sewage and media containing fibrous impurities. It is widely used in various fields such as petroleum, chemical, metallurgical, light industry, papermaking, power plants, refrigeration, etc. Ball valves are an important type of valve that are widely used in fields such as petrochemicals and long-distance pipelines. The closing element of a ball valve is a ball (or partial ball) with a hole, which rotates with the valve stem to open or close the valve. The ball valve can be fully closed and opened by rotating 90 degrees. Compared with gate valves and globe valves of the same specifications, the ball valve has a smaller volume and lighter weight, making it easier to install pipelines.
