What are the advantages of pneumatic ball valves?

Pneumatic ball valve has compact structure, reliable sealing, simple structure and convenient maintenance. The sealing surface and spherical surface are always in a closed state, which is not easy to be eroded by the medium, and is easy to operate and maintain. It is suitable for general working media such as water, solvent, acid and natural gas. It can be used to cut off or connect the medium in the pipeline, and can also be used for the regulation and control of the fluid. Compared with other valve types, the pneumatic ball valve has the angular stroke output torque, the opening is fast, stable and reliable, and it is widely used. Some advantages, such as the following.

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. Reliable sealing of the valve stem: Since the valve stem only moves in imitation rotation and does not move up and down, the packing seal of the valve stem is not easy to be damaged, and the sealing capacity increases with the increase of the pressure of the medium.

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.
