a valve actuator is the mechanism for opening and closing a valve. manually operated valves require someone in attendance to adjust them using a direct or geared mechanism attached to the valve stem. power-operated actuators, using gas pressure, hydraulic pressure or electricity, allow a valve to be adjusted remotely, or allow rapid operation of large valves. power-operated valve actuators may be the final elements of an automatic control loop which automatically regulates some flow, level or other process. actuators may be only to open and close the valve, or may allow intermediate positioning; some valve actuators include switches or other ways to remotely indicate the position of the valve.
