Describe the difference between a direct-acting and a reverse-acting actuator.
In a direct-acting actuator, the valve moves in the same direction as the actuator stem; in a reverse-acting actuator, the valve moves in the opposite direction.
Direct-acting actuators are generally faster than reverse-acting actuators.
