Siemens SQM33.550A9 actuator

Siemens SQM33.550A9 actuator: precision control for modern electronic combustion systems. Buying Siemens SQM33.550A9 means equipping your burner with a high-tech electric actuator of a new generation. This model is specifically designed to work with electronic combustion managers of the LMV2 and LMV3 series and provides exceptional positioning accuracy for air and gas dampers thanks to a stepper motor with a resolution of 0.2°. Purpose and application: The Siemens SQM33.550A9 actuator is intended for rotating air dampers, gas throttles, and liquid fuel valves in burner devices. It is used in combustion control systems requiring high precision in maintaining the fuel-air ratio. Main applications: Industrial burners with electronic control systems LMV2/LMV3; Modulating burners of medium and high power; Boiler plants with precise mixture composition control; Heat generating plants with low NOx emission requirements. The actuator is controlled by combustion managers that calculate the required damper position in real time to achieve optimal combustion at the current load.
