Advantages:

1. The thrust bearing reduces the stem friction torque, ensuring long-term smooth and flexible operation of the stem.

2. Anti-static function: Springs installed between the ball, stem, and body can conduct static electricity generated during the switching process.

3. Due to the excellent self-lubricating properties of materials such as polytetrafluoroethylene, friction loss with the ball is minimal, resulting in a long service life for pneumatic ball valves.

4. Low fluid resistance: Pneumatic ball valves have the lowest fluid resistance among all valve categories. Even reduced-diameter pneumatic ball valves exhibit very low fluid resistance.

5. Reliable stem sealing: Since the stem only rotates and does not move up and down, the stem packing seal is less prone to damage, and the sealing capability increases with higher medium pressure.

6. Excellent seat sealing performance: Sealing rings made of elastic materials like polytetrafluoroethylene are easy to seal structurally, and the sealing capability of pneumatic ball valves improves with increasing medium pressure.

7. Low fluid resistance: Full-bore ball valves have virtually no flow resistance.

8. Simple structure, compact size, and lightweight.

9. Tight and reliable: With two sealing surfaces and the widespread use of various plastics for ball valve sealing materials, they offer excellent sealing performance and can achieve complete sealing. They are also widely used in vacuum systems.

10. Easy operation and quick opening/closing: Only a 90° rotation is required to go from fully open to fully closed, making remote control convenient.

11. Easy maintenance: The simple structure of ball valves, with generally removable sealing rings, makes disassembly and replacement straightforward.

12. When fully open or closed, the sealing surfaces of the ball and seat are isolated from the medium, preventing erosion of the valve sealing surfaces by the medium.

13. Wide range of applications: Suitable for diameters ranging from a few millimeters to several meters, and from high vacuum to high pressure.

14. Due to the wiping action during opening and closing, ball valves can be used with media containing suspended solid particles.

15. High processing precision and expensive cost; not suitable for high-temperature use. If impurities are present in the pipeline, they can easily clog the valve, preventing it from opening.
