Devices designed to automatically control and monitor the position of valves, in relation to their open or closed positions.
Electric Valve Actuators (415 suppliers)
Electric valve actuators mount on valves which, in response to a signal, automatically move to a desired position using an outside power source. Single-phase or three-phase AC or DC motors drive a combination of gears to generate the desired torque level.
