1. Anti-static function: A spring is set between the ball, the valve stem and the valve body, which can export the static electricity generated during the switching process.
2. Since PTFE and other materials have good self-lubrication, the friction loss with the ball is small, so the service life of the pneumatic ball valve is long.
3. Small fluid resistance: Pneumatic ball valve is the one with the smallest fluid resistance among all valve categories. Even the reduced-diameter pneumatic ball valve, its fluid resistance is quite small.
4. Reliable valve stem sealing: Since the valve stem only rotates and does not move up and down, the packing seal of the valve stem is not easy to be damaged, and the sealing ability increases with the increase of the medium pressure.
5. The valve seat has good sealing performance: the sealing ring made of elastic materials such as PTFE is easy to seal in structure, and the sealing ability of the pneumatic ball valve increases with the increase of the medium pressure.
6. Simple structure, small size and light weight.
7. Tight and reliable. It has two sealing surfaces, and the sealing surface materials of the ball valve are widely used in various plastics, which have good sealing performance and can achieve complete sealing. It has also been widely used in vacuum systems.
8. Easy to operate, open and close quickly, just rotate 90° from fully open to fully closed, which is convenient for long-distance control.
9. It is easy to maintain, the ball valve has a simple structure, the sealing ring is generally movable, and it is more convenient to disassemble and replace.
10. When fully open or fully closed, the sealing surfaces of the ball and the valve seat are isolated from the medium, and the sealing surface of the valve will not be eroded when the medium passes through.
11. Wide range of applications, diameters ranging from small to several millimeters, large to several meters, and can be applied from high vacuum to high pressure.
12. Due to the wiping property of the ball valve during the opening and closing process, it can be used in the medium with suspended solid particles.
