Product Details

Product description
Pneumatic ball valve is equipped with pneumatic actuator. Pneumatic actuator execution speed is relatively fast, and do not require workers to pro force, to a large extent, saving human resources and time. This type of valve in the pipeline should generally be installed horizontally. Pneumatic ball valve development and evolution of the working principle of pneumatic ball valve is evolved from the cut-off valve. It has the same rotation 90 degrees to lift the action, the difference is that the plug body is a sphere, a circular through hole or channel through its axis. The ratio of the spherical surface and the channel port should be such that when the ball is rotated 90 degrees, the inlet and outlet should be all spherical, thereby cutting off the flow.
