Structural characteristics of pneumatic ball valve:

1, fluid resistance is small, ball valve is the smallest of all types of fluid resistance, even the diameter ball valve, its fluid resistance is quite small.

2, thrust bearings to reduce the valve friction torque pneumatic rod, stem can make long-term operation smooth and flexible.

3, seat sealing performance is good, the use of PTFE and other elastic materials made of sealing ring, the structure is easy to seal, and ball valve sealing capacity increases with the increase in medium pressure.

4, the valve stem seal is reliable, because the stem only for imitation rotation transported without movement, stem packing seal is not easy to damage, and sealing ability increased with the increase of the pressure medium.

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

6, downloading the stem and the stem head convex order to prevent the stem spray, such as stem seal damage caused by fire, convex order and the body can be formed between the metal contact, to ensure that the valve stem seals.

7, anti-static function: in the ball, stem, valve between the spring, the switch process can be generated electrostatic export
