The electric ball valve is a rotary ball valve with a rotation angle of 90°. It has excellent sealing performance, large circulation capacity, small flow resistance coefficient, simple structure, convenient maintenance and long service life. The valve body passage and the connecting pipe are equal in diameter and form a diameter. It can flow almost without loss. It is equipped with DKJ-II and III actuators and is equipped with high-performance actuators such as Japanese tooling and West Germany Omron. The products are usually used in places with strict sealing requirements. In addition to controlling gas, liquid and steam media, they are also suitable for controlling sewage and media containing fibrous impurities. They are widely used in petroleum, chemical, metallurgy, light industry, paper making, power station, refrigeration, etc. Work area.
　　Ball valve is an important type of valve, widely used in petrochemical, long-distance pipelines and other fields. The closing member of the ball valve is a spherical ball (or a partial ball) with a hole that rotates with the valve stem to open or close the valve.
　　The ball valve can be fully closed when rotated by 90°. Compared with gate valves and globe valves of the same specification, the ball valve is small in size and light in weight, which is convenient for pipeline installation.
