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 one of the most small fluid resistance in all valve classes, even if it is a reduced diameter ball valve, its fluid resistance is quite small.
2. The thrust bearing reduces the friction torque of the valve stem, which can make the valve stem operate smoothly and flexibly for a long time.
3, the sealing performance of the valve seat is good, the pneumatic ball valve is made of polytetrafluoroethylene and other elastic materials, the structure is easy to seal, and the valve sealing capacity of the ball valve increases with the increase of the medium pressure.
4, the valve stem seal is reliable, because the valve stem is only as if rotating without lifting movement, the packing seal of the valve stem is not easy to destroy, and the sealing capacity increases with the pressure of the medium.
5, because polytetrafluoroethylene and other materials have good self-lubrication, and the friction loss with the ball is small, so the service life of the ball valve is long.
6, the lower mounted valve stem and valve stem head convex step to prevent the valve stem ejecta, such as fire caused by the valve stem seal damage, the convex step and the valve body can also form metal contact to ensure the valve stem seal.
7, anti-static function: set the spring between the ball, valve stem and valve body, which can export the static electricity generated by the switching process.
