Electric ball valve is a relatively new type of ball valve, it has its own unique structure of some advantages, such as the switch friction, sealing easy to wear, opening and closing torque is small. This will reduce the size of the actuator fitted. With multi-turn electric actuator, the media can be adjusted and cut off. Widely used in petroleum, chemical, urban water supply and drainage requirements severely cut off the conditions.
Electric ball valve is mainly used in the pipeline to cut off, distribute and change the flow direction of the medium. Ball valve is widely used in recent years, a new type of valve, which has the following advantages:
1. Fluid resistance is small, the resistance coefficient and the same length of the pipe section.
2. Simple structure, small size, light weight.
3. Tight and reliable, the current ball valve sealing surface material widely used plastic, good sealing, vacuum system has also been widely used.
4. Easy to operate, quickly open and close, as long as the full open to 90 degrees off, easy to remote control.
5. Easy maintenance, ball valve structure is simple, the seals are generally active, demolition and replacement are more convenient.
6. In the fully open or fully closed, the sealing surface of the ball and valve seat and media isolation, media will not cause erosion of the valve sealing surface.
7. Wide range of applications, the path from small to a few millimeters, up to a few meters, from high vacuum to high pressure can be applied. When the ball is rotated 90 degrees, the sphere should appear entirely at the entrance and exit, thus interrupting the flow.
