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
