Rotary Actuators
SM-1700 Series of Rotary Actuators
 
The SM-1700 Series are 90° to 360° rotary actuators internally geared to produce up to 2400 in. lbs. (271 Nm) of torque and offer continuous modulation. This actuator series uses high efficiency spur gears that are designed to meet the exacting requirements for closed-loop, modulating positioning control. The SM-1700 Series is ideally suited for dampers, vanes, valves and other process control applications requiring exact positioning control.

All SM-1700 Series actuators are also available with an internal amplifier (excluding SM-1740 & SM-1760). These amplifiers are all full-featured ac switching devices designed to work seamlessly with the actuator for closed loop control.
