Siemens control motors are highly versatile modulating actuators used for the positioning of flow control valves, butterfly valves, dampers, or any application requiring rotary motion.
SQM40/41 Series Control Motors
Siemens Combustion Controls SQM4 Control Motor Actuator

The Siemens SQM4 Synchro is a cost effective modulating actuator with up to 90 in-lbs and 12 or 25 second drive times for 90 degrees.

  • NEMA 4 – No need for weather shields
  • No restrictions on mounting orientation – No more elaborate linkages to keep the shaft horizontal!
  • The modulating input versions accept 2-10 Vdc, 4-20 mA or 0-135 ohm control signals


SQM5 Series Control Motors
Siemens Combustion Controls SQM5 Control Motor Actuator

The Siemens SQM5 is available in a wide range of torque ratings from 90 to 400 in-lbs. and running times of 8 to 50 seconds. A selection of exchangeable circuit boards provide a variety of functions including zero and span adjustment, parallel or master/slave operation, split range control, input signal override and selectable electronic linearization.

  • Six easily accessible internal switches
  • Auto/manual switch allows easy adjustments
  • Externally visible shaft position indicator
  • Highly modulating accuracy/rotational resolution
  • Low hysteresis actuator with double-offset drive and potentiometer gearing
