It has the same action of rotating 90 degrees, except that the cock body is a sphere with a circular through hole or channel through its axis. The ball valve is mainly used to cut off, distribute and change the flow direction of the medium in the pipeline. It only needs to rotate 90 degrees and a small rotational torque to close tightly.
main feature
1. The fluid resistance is small, and the full-diameter ball valve has basically no flow resistance.
2. Simple structure, small size and light weight.
3. Tight and reliable. It has two sealing surfaces, and the sealing surface materials of ball valves currently use various plastics, which have good sealing properties and can achieve complete sealing. in real
It has also been widely used in air systems.
4. Easy to operate, quick to open and close, just rotate 90° from fully open to fully closed , convenient for long-distance control.
5. It is easy to maintain. The ball valve has a simple structure and the sealing rings are generally movable, making it easy to disassemble and replace.
6. When fully open or fully closed, the sealing surfaces of the ball and valve seat are isolated from the medium. When the medium passes, it will not cause erosion of the valve sealing surface.
7. It has a wide range of applications, with diameters ranging from a few millimeters to several meters, and can be applied from high vacuum to high pressure.
8. Since the ball valve has wiping properties during the opening and closing process, it can be used in media with suspended solid particles.
