Pneumatic ball valve is mainly used for cut off or through the medium pipeline, also can be used for the regulation and control fluid, it and other valve class of advantages compared with:

1, fluid resistance small, ball valve is all of the fluid in a kind of least resistance, even shrink diameter ball valve, its fluid resistance also is fairly small.

2, thrust bearings reduce stem friction torque, can make the stem long-term stable flexible operation.

3, seat sealing performance is good, the ptfe etc elastic material made of the sealing ring, structure easy to seal, and the valve sealing ball valves with ability of increased media pressure increase.

4, stem sealing is reliable, because stem only make as the rotation and don't do lifting movement, the valve stem packing seal is not easy to damage, and sealing ability with the medium pressure increase.

5, because of ptfe etc material has good self lubrication, and the friction losses small sphere, the ball valve long service life.

6, remove theatrical makeup and costume type valve stem and stem head convex order prevent stem jet, such as the fire caused stem seal failure, convex order and body still can form between metal contact, ensure stem seal.

7, anti-static function: in the sphere, the stem, the body set up between spring will switch processes that produce static and export of actuators.
