Siemens SQN31.101A2700 actuator

Siemens SQN31.101A2700 actuator: fast and reliable air damper control. Buying Siemens SQN31.101A2700 means equipping your burner with a high-speed electric actuator for precise air supply regulation. This model is the basic one in the SQN31 line and is specifically designed for gas and oil burners of small and medium power. Purpose and application: The Siemens SQN31.101A2700 actuator is intended for rotating air dampers of burner devices, controlling the precise ratio of fuel and air. It is integrated into single-stage, two-stage, or modulating burners of small and medium power. Main functions of the actuator: Damper positioning during ignition — supplying the amount of air necessary for safe ignition; Damper control during burner operation at low and high power; Opening the damper during combustion chamber purge to remove residual gases. The actuator is compatible with P-PI or PID controllers (e.g., RWF40...), as well as with burner controls LOA..., LMO..., LMG..., LFL...
