The pneumatic ball valve is a ball valve equipped with a pneumatic actuator. The execution speed of the pneumatic actuator is relatively fast, and the fastest switching speed is 0.05 seconds/time, so it is usually also called a pneumatic quick shut-off ball valve. Pneumatic ball valves are usually equipped with various accessories, such as solenoid valves, air source treatment triples, limit switches, positioners, control boxes, etc., to achieve local control and remote centralized control, and the valve can be controlled in the control room. , do not need to go to the scene or bring manual control at high altitudes and dangerous areas, which greatly saves human resources, time and safety.

The working principle of the pneumatic ball valve is to make the valve unblocked or blocked by rotating the spool. Pneumatic ball valve is easy to switch, small in size, can be made into a large diameter, reliable in sealing, simple in structure, convenient in maintenance, and the sealing surface and spherical surface are always in a closed state, which is not easy to be eroded by the medium, and has been widely used in various industries.
