1.The thrust bearing reduces the friction torque of the valve stem, which can make the valve stem operate smoothly and flexibly.
2. Anti-static function: a spring is set between the ball, valve stem and valve body, which can lead out the static electricity generated during the switching process.
3. Since materials such as polytetrafluoroethylene have good self-lubricating properties and small friction loss with the ball, the pneumatic ball valve has a long service life.
4. Small fluid resistance: Pneumatic ball valves are the one with the smaller fluid resistance in all valve categories. Even the reduced diameter pneumatic ball valves have relatively small fluid resistance.
5. 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 medium pressure.
6. The valve seat has good sealing performance: the sealing ring made of PTFE and other elastic materials is easy to seal, and the valve sealing capacity of the pneumatic ball valve increases with the increase of the medium pressure.
7. The fluid resistance is small, and the full-bore ball valve basically has no flow resistance.
8. Simple structure, small size and light weight.
9. Close 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 sealing. It has also been widely used in vacuum systems.
10. Convenient operation and rapid opening and closing. The ball valve only needs to rotate 90° from fully open to fully closed, which is convenient for remote control.
