The SQM45 actuators are suited for driving oil pressure controllers, butterfly valves, dampers or for use on other applications that require rotary motion. Areas of application are oil and gas burners of medium to larger capacity, as well as thermal process plants.
The actuators are used primarily for the load-dependent control of the gas flow, oil volume and combustion air volume in connection with the electronic ratio control LMV5.
