BKH Ball Valves/BKH3K Ball Valves Company introduces the advantages of pneumatic ball valves:
1. The thrust bearing reduces the friction torque of the valve stem, which can make the valve stem operate smoothly and flexibly for a long time.
2. 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.
3. Due to the good self-lubricating properties of PTFE and other materials, the friction loss with the ball is small, so the service life of the pneumatic ball valve is long.
4. 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.
5. The valve stem seal is reliable: because 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.
6. 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.
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. 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.
10. Easy operation, quick opening and closing, only need to rotate 90° from fully open to fully closed, which is convenient for long-distance control.
11. 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.
12. When fully open or fully closed, the sealing surfaces of the ball and the valve seat are isolated from the medium, and when the medium passes through, it will not cause erosion of the valve sealing surface.
13. 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.
14. Because the ball valve has wiping property during the opening and closing process, it can be used in the medium with suspended solid particles.
15. High processing precision and high cost. It is not suitable for use in high temperature. If there are impurities in the pipeline, it is easy to be blocked by impurities, resulting in the valve cannot be opened.
