The pneumatic ball valve is mainly used in the flow pipeline for quick cutting off, distributing and changing the medium. The structure of pneumatic ball valve mainly has two types of structures: O type and V type ball core. The O type ball valve core is a floating precision casting, with the same diameter as the pipeline port, which is mainly used as a cut-off switch; The other is V-shaped ball core, which adopts a fixed structure, with V-shaped notch on the ball core. After the positioner is installed on the actuator, the proportion of fiber and granular media can be adjusted.

Close the valve hole to gradually ventilate, and then use a large air pressure to push the internal piston out completely. When using this method, pay attention to gradually ventilate the pneumatic butterfly valve, otherwise the piston will suddenly spray out. This situation is very dangerous, which may cause injury to the operator. Remove the stuck spring on the cylinder shaft completely, Then take out the cylinder shaft from the other end of the valve. After the above preparations are completed, all the components inside the valve can be cleaned in a centralized way, and lubricating grease needs to be added to the components.
