Advantages of pneumatic ball valves compared with other valves

Pneumatic ball valve is mainly used to cut off or connect the medium in the pipeline, can also be used for fluid regulation and control, its advantages compared with other valves:

1, the fluid resistance is small, pneumatic ball valve is all valves in the fluid resistance is small, even if the ball valve, the fluid resistance is quite small.

2, the thrust bearing reduces the friction torque of the stem, can make the stem long-term operation stable and flexible.

3, seat sealing performance is good, pneumatic ball valve using ptfe and other elastic materials made of the sealing ring, the structure is easy to seal, and the ball valve sealing capacity with the increase of the media pressure and increase.

4, the stem seal is reliable, because the stem is only as if rotating without lifting movement, the packing seal of the stem is not easy to damage, and the sealing capacity increases with the increase of the pressure of the medium.

5, due to ptfe and other materials have good self-lubrication, and the ball friction loss is small, so the service life of the ball valve is long.

6, lower mounted stem and stem head convex steps to prevent the stem out, such as the fire caused damage to the stem seal, convex steps and valve body can also form a metal contact, to ensure the stem seal.

7. Anti-static function: spring is set between the ball, valve stem and valve body to export the static electricity generated during the switching process.
