Rotork SM-5000 Series Rotary Actuator

Brand: Rotork PLC

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.

The SM-5000 series actuators utilize a scotch-yoke drive for transforming linear motion from a traveling nut to the rotary motion on the output shaft.
