1. The fluid resistance of the ball valve is small, and the full diameter ball valve basically has no flow resistance.
2. The ball valve has simple structure, small volume and light weight.
3. The ball valve is Tight and reliable. It has two sealing surfaces, and at present, various plastics are widely used as the sealing surface materials of ball valve, which has good sealing performance and can realize complete sealing. It has also been widely used in vacuum systems.
4. The ball valve is easy to operate and open and close quickly. It only needs to rotate 90° from full open to full close, which is convenient for remote control.
5. The maintenance of the ball valve is convenient, the structure of the ball valve is simple, the sealing ring is generally movable, and the disassembly and replacement are relatively convenient.
6. When fully open or fully closed, the sealing surface of the ball and valve seat shall be isolated from the medium. When the medium passes through, it will not cause the erosion of the valve sealing surface.
7. It has a wide range of applications, ranging from small to several millimeters and large to several meters. It can be applied from high vacuum to high pressure.
8. Because the ball valve is wiping during opening and closing, it can be used in media with suspended solid particles.
