Siemens SQM56.687A8 Servo motor | Actuator - 24vv

The SQM5 actuators are designed to drive air and gas dampers, areas of application are oil and gas burners of medium to larger capacity. The actuators are used primarily for the load-dependent control of the gas flow, oil volume and combustion air volume.

Can be used to replace a Honeywell Mod III or Mod IV actuator when used with the AGA57.3 bracket.
