In addition, this can also increase the air pressure inside the ball valve to ensure a completely closed state inside. It is completely different from the elastic ball valve, and the upper and lower parts of the ball valve are equipped with bearings, so that a torsional operation can be carried out. Most of them are installed in large caliber pneumatic ball valves, In order to reduce the friction between the ball valve and the equipment during operation and cause certain density impact, a lubricant component will be added here, thus forming a protective layer for the ball valve.

And pay attention to the problem of working pressure. If the working pressure is too low when introducing, it will cause sealing or invalidity. If the working pressure is too high, the grease injection nozzle will be very easy to block. The maintenance of the pneumatic ball valve is related to the normal availability and service life of the pneumatic ball valve, and the overall cleaning is required. If the pneumatic ball valve is cleaned, the applied organic solvent must not produce destructive exothermic reaction with the parts to be cleaned, and simple rust prevention treatment can be accepted,
