Single and Double Acting Actuators
There are basically two types of actuators : single action and double action.
Single action is a control valve that is driven by the air output of the control valve positioner on one side (side open or close) while the other side is moved with the aid of a spring or a membrane.
Double action is a control valve that is driven by the output air of control valve positioner on both sides (sides open and close).
In typical application of the ball valve, control valve, and choke valve, there are two types of actuator that is used, the spring return (or single acting) actuator and the double acting actuator.
