Pneumatic Ball Valve: Working Principle and Features

The working principle of pneumatic ball valve is to use compressed air into the pneumatic actuator, so that the piston of the pneumatic actuator movement, and then rotate the valve sphere, so as to realize the switch control of the valve. Pneumatic ball valve valve body is equipped with a spherical cutting body, the sphere rotates around the longitudinal axis, thus changing the state of the media circulation channel. Its average diameter of the sphere is aligned with the pipeline transmission axis, which has a small fluid resistance. When the compressed air in the pneumatic actuator disappears, the valve sphere will be subject to the role of elastic force and back to the position.
