The pneumatic ball valve only needs to use the pneumatic actuator to rotate the air source by 90 degrees and a small torque to close tightly. The completely equal valve body cavity provides a low resistance, straight-through flow path for the medium. It is generally believed that ball valves are most suitable for direct opening and closing, but recent developments have designed ball valves so that they can be used for throttling and flow control. The main feature of the ball valve is its compact structure, easy operation and maintenance, suitable for general working media such as water, solvent, acid and natural gas, and also suitable for media with harsh working conditions, such as oxygen, hydrogen peroxide, methane and ethylene. The ball valve body can be integral or combined.

The working principle of the pneumatic ball valve is to make the valve unblocked or blocked by rotating the valve core. Pneumatic ball valve switch is light, small size, can be made into large diameter, reliable sealing, simple structure, convenient maintenance, sealing surface and spherical surface are often closed, not easy to be eroded by medium, and are widely used in various industries. Pneumatic ball valve and plug valve are the same type of valve, only its closing part is a sphere, and the sphere rotates around the center line of the valve body to achieve opening and closing.
