Pneumatic diaphragm valve is based on the diaphragm serving as a power communication line, and the control system controls the medium flow by controlling the pressure difference.

When the pneumatic control signal acts on the pneumatic actuator, the action of the cylinder will cause the volume of the air chamber on the diaphragm to change, thereby regulating the flow rate.
