What advantages does sanitary pneumatic ball valve have when compared with other valves

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

 

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

 

3, seat sealing performance is good, PTFE (PTFE) and other elastic materials made of sealing ring, structure is easy to seal, and the ball valve sealing capacity with the increase of medium pressure and increase;

4. The thrust bearing can reduce the friction torque of valve stem, which can make the valve stem operate smoothly and flexibly for a long time;

 

5, small fluid resistance, ball valve is all the valve class of fluid resistance is the least, even if the reduced diameter ball valve, its fluid resistance is quite small.

 

6. Convex steps of lower stem and stem head prevent spout of stem. In case of damage of stem seal caused by fire, metal contact can be formed between convex steps and valve body to ensure stem seal;

 

7, pneumatic ball valve is mainly used to cut off or put through the medium in the pipeline, can also be used for fluid regulation and control, because 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.
