Structure and principle of electric ball valve

The electric ball valve has the advantages of small size, light weight, small installation size, small driving torque, simple operation, agility, etc. it can be opened and closed quickly only by rotating 90 °, and has good flow regulation effect and sealing characteristics. In the application scope of large and medium caliber, medium and low pressure, the electric ball valve is the leading valve 1、 In the pipeline, it is mainly used to cut off, distribute and change the flow direction of medium. When the electric ball valve is fully opened, there is no resistance when the medium flows through the ball core port, so the pressure drop through the valve is very small, so it has better flow control characteristics.

There are many kinds of electric ball valves, which are generally divided into two categories according to different structural forms, i.e. O-type structure and V-type structure. The ball openings of the two types are different and their applications are different. O-type is generally suitable for shut-off use, occasionally for adjustment, while V-type is more suitable for adjustment (with large adjustable ratio).
