Classification and characteristics of pneumatic pneumatic ball valves Pneumatic pneumatic ball valves are a set of devices equipped with pneumatic actuators, solenoid valves, limit switches, air supply triplets and other accessories. Only need the pneumatic actuator to rotate 90 degrees with the air source and a small rotating torque to close tightly. The completely equal inner cavity of the valve body provides a straight flow passage with little resistance for the medium. It is generally believed that pneumatic ball valves are most suitable for direct opening and closing, but recent development has designed pneumatic ball valves to be used for throttling and flow control. It is convenient for pneumatic and pneumatic ball valves to control the opening and closing of valves in a unified way.

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.
