The SM-1700/5000 Series of rotary actuators are internally geared to produce up to 12,500 ft.lbs. (16,950 Nm) of torque, and offer continuous modulation. They are ideally suited for dampers, vanes, valves and other process control applications requiring exact positioning control.SM-1700Torques from 50 to 200 ft.lb.
