Pneumatic ball valve in the daily production and life of the role of more and more, it gradually replaced other valve types, this valve type has more advantages.

The pneumatic ball valve only needs to be operated with gas rotation of 90 degrees and a small torque to close tightly. Fully equal valve body cavity for the medium to provide little resistance, through the flow channel. Ball valves are generally considered suitable for open and close use, but recent developments have designed them for throttling and flow control. The main characteristics of the ball valve is itself compact structure, easy to operate and maintain, suitable for water, solvent, acid and natural gas and other general working medium, but also suitable for harsh working conditions of the medium, such as oxygen, hydrogen peroxide, methane and ethylene. The ball valve body may be integral or modular.

Pneumatic actuators are relatively fast, and do not require workers to do it themselves, to a great extent to save human resources and time. Pneumatic ball valves are evolved from globe valves. It has the same rotation 90 degree lift action, the difference is that the plug body is a sphere, with a circular through hole or channel through its axis. The ratio between the sphere and the passage should be such that when the sphere is rotated 90 degrees, the sphere should be presented at the inlet and outlet to cut off the flow.
