Product Description:
ZAJO electric O-type shut-off ball valve (referred to as cut-off ball valve) is a rotary control valve, which is an actuator unit in the electric unit assembly instrument cluster. The shut-off ball valve body has low flow channel resistance, large flow coefficient, and the cylindrical through-hole ball spool has a shear function to control viscous media with fibers and particles. The shut-off ball valve is equipped with a small, sturdy, high-precision actuator that receives the ON-OFF action, the action is sensitive, and the corner direct indication and feedback are widely used in the gas, steam, liquid transportation pipeline of petroleum, chemical, papermaking, metallurgy, sewage treatment and other production departments to open and cut off the medium, so as to achieve the production process according to a certain specification.
Product Features:
Electric ball valve is a kind of rotary ball valve with a turning angle of 90°, excellent sealing performance, large flow capacity, small flow resistance coefficient, simple structure, convenient maintenance, long service life, valve body channel and connecting pipe diameter are equal and one diameter, and the medium can flow through almost without loss. Equipped with DKJ-II AND III actuators, it is equipped with 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, steam medium, but also suitable for controlling sewage and media containing fibrous impurities, widely used in petroleum, chemical, metallurgy, light industry, papermaking, power station, refrigeration and other work fields. Ball valves are an important type of valve that are widely used in petrochemical, long-distance pipelines and other fields. The closing part of the ball valve is a ball (or part of the ball) with a hole, and the ball rotates with the valve stem to realize the opening or closing of the valve. The ball valve can be fully closed and opened by rotating 90°, which is smaller and lighter than the gate valve and globe valve of the same specification, which is convenient for pipeline installation.
