The pneumatic actuator of the pneumatic diaphragm top handwheel type regulator is installed at the top of the valve body, and is also equipped with a handwheel operating device, which is convenient to manually control the opening and closing of the valve in case of emergency. When the air source pressure in the pneumatic actuator changes, the piston in the pneumatic actuator will push the film, so as to promote the movement of the valve core, to achieve flow regulation.
