The main components of the pneumatic flow control valve include the pneumatic
actuator and valve body. When the air source signal acts on the pneumatic diaphragm, a
displacementwill be generated. This displacement is transmitted to the actuator, pushing
the valve spool to move, thereby changing the flow cross-sectional area of the regulating
valve and achieving flow regulation.
