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 like PTFE, 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 types. Even reduced-bore pneumatic ball valves exhibit very low fluid resistance.

5. Reliable stem sealing: Since the stem only rotates without lifting, the stem packing seal is less prone to damage, and sealing capacity increases with higher media pressure.

6. Excellent seat sealing performance: Sealing rings made of elastic materials like PTFE are easy to seal structurally, and the sealing capacity of pneumatic ball valves improves with increasing media 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. It features two sealing surfaces, and the sealing materials for ball valves widely use various plastics, ensuring good sealing and complete tightness. They are also widely used in vacuum systems.

10. Easy operation and quick opening/closing; only a 90° rotation is needed from fully open to fully closed, facilitating remote control.

11. Easy maintenance: The ball valve has a simple structure, and the sealing rings are generally movable, making disassembly and replacement convenient.

12. When fully open or closed, the sealing surfaces of the ball and seat are isolated from the media, preventing erosion of the valve sealing surfaces when media flows through.

13. Wide range of applications: Suitable for diameters 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 cause blockages, preventing the valve from opening.
