Advantages of pneumatic ball valve

Advantages of pneumatic ball valve

1. The thrust bearing reduces the friction torque of the valve stem, which can make the long-term operation of the valve stem stable and flexible.

2. Anti static function: spring is set between the ball, valve stem and valve body to export the static electricity generated in the process of switching.

3. As PTFE and other materials have good self-lubricating property and small friction loss with the ball, the service life of pneumatic ball valve is long.

4. Small fluid resistance: pneumatic ball valve is one of the lowest fluid resistance in all valve categories, even for reduced diameter pneumatic ball valve, its fluid resistance is also quite small.

5. Reliable sealing of valve stem: as the valve stem only rotates without lifting, the packing seal of valve stem is not easy to be damaged, and the sealing capacity increases with the increase of medium pressure.

6. Good sealing performance of valve seat: the sealing ring made of PTFE and other elastic materials is easy to seal, and the sealing capacity of pneumatic ball valve increases with the increase of medium pressure.

7. Small fluid resistance, full bore ball valve basically no flow resistance.

8. It has the advantages of simple structure, small volume and light weight.

9. Tight and reliable. It has two sealing surfaces, and the sealing surface material of ball valve is widely used all kinds of plastics, which has good sealing performance and can realize complete sealing. It has been widely used in vacuum system.

10. Easy to operate, open and close quickly, from full open to full close as long as 90 degrees °， It is convenient for remote control.

11. Easy maintenance, simple ball valve structure, sealing ring is generally mobile, disassembly and replacement are more convenient.

12. When the valve is fully opened or closed, the sealing surface of the ball and the valve seat is isolated from the medium, and the erosion of the sealing surface of the valve will not be caused when the medium passes through.

13. Wide range of applications, diameter from small to a few millimeters, up to a few meters, from high vacuum to high pressure can be applied.

14. Because the ball valve has wiping property in the process of opening and closing, it can be used in the medium with suspended solid particles.

15. High processing accuracy, high cost, high temperature should not be used, such as impurities in the pipeline, easy to be blocked by impurities, resulting in the valve can not be opened.
