SM-1700/SM-5000

SM-1700/5000 actuators are internally geared to produce up to 16,950 Nm (12,500 lbf.ft) of torque, continuous modulation, with automatic torque limiting and self-locking drive system to hold in last position and prevent backdriving. They are ideally suited for dampers, vanes, valves and other process control applications requiring exact positioning control.
