Product Introduction:  

Pneumatic ball valve is mainly used to truncate or connect the medium in the pipeline, can also be used for fluid mediation and control, compared with other valves, has the following advantages:  

1. Small fluid resistance, ball valve is one of the least fluid resistance of all valves, even reduced diameter ball valve, its fluid resistance is quite small.  

2. The thrust bearing reduces the friction torque of the valve stem, so that the valve stem can be operated smoothly and flexibly for a long time.  

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

4. The stem seal is reliable. Because the stem only moves as if without lifting, the packing seal of the stem is not easy to destroy, and the sealing capacity increases with the pressure of the medium.  

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

6. Lower type stem and stem head convex order to prevent stem ejection, such as fire caused stem seal damage, convex order and valve body can also form metal contact, to ensure stem seal.  

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