Rotary Actuators
SM-1000 Series of Rotary Actuators
 
The SM-1000 Series of multi-turn, rotary actuators, designed to meet the exacting requirements for closed-loop modulating positioning control. Designed for low to medium torque rotary applications, these actuators are capable of accepting analog current and voltage command signals. The brushless stepper motor design provides smooth, highly accurate positiong, with positive position-lock when not in motion and powered. The SM-1000 Series is ideally suited for regulators, pilot valves, small quater-turn valves, choke valves and dampers.

All SM-1000 Series actuators come with a standard digital internal amplifier. These amplifiers are all full- featured devices disgned to work seamlessly with the actuator for closed loop control.
