The adjusting screws(pneumatic actuator)
at both ends can adjust the opening angle of the valve.
The same specifications include double acting type and single acting type (spring return).
The direction can be selected according to the needs of the valve, clockwise or counterclockwise.
Install solenoid valve, positioner (opening indication), Messenger, various limit switches and manual operation devices according to the needs of users.
Shortcoming of the pneumatic actuator
The control accuracy of the pneumatic actuator
is low, and the double acting pneumatic actuator cannot return to the preset position after the air source is cut off. The single acting pneumatic actuator can return to the preset position by relying on the spring after the air source is cut off
