Discuss the role of pneumatic ball valve in the pipeline system

the inside of the ball valve opening and closing is a sphere, its main function is to adjust the medium in the pipeline effect, and this sphere open-close part for fluid resistance is small, impact will also corresponding reduced. So the open-close part will be more durable, and ball valve is also joined the pneumatic actuators, enables the combination form of pneumatic ball valve to play a good role in the pipeline. Now, most of the regulating ball valve is used on the pneumatic actuators, this device because it is connected with ball valve stem, so play a control effect is also passed through the valve stem. In the pipeline system, when the need for the adjustment of the medium, the pneumatic device can through to the compressed air after the power to drive actuators internal piston and the piston is connected with pneumatic ball valve stem, so the piston movement, to play with the movement of the valve stem, and the valve stem is connected with the open-close part, so the valve rod rotation also represents the internal operation of the opening and closing of the sphere, and the movement of the ball inside the valve body is the medium in pipeline system has brought certain adjustment.
