Product Overview

The Siemens SQN1 series burner servomotors are compact actuators used to control air dampers and fuel control valves in industrial burner systems. These actuators help regulate the combustion process by adjusting the air-fuel ratio depending on the burner load requirements.

The SQN1 series is designed mainly for small and medium-capacity burners, where low torque is sufficient for damper or valve positioning. These actuators operate together with burner control systems or electronic fuel-air ratio controllers to regulate combustion output.

The servomotor uses a synchronous motor with an integrated gear mechanism, which converts electrical control signals into precise rotational movement for positioning air or gas dampers.

Depending on the version, the actuator can be installed with Siemens burner management systems such as LMV2 or LMV3, enabling accurate load-dependent control of burner components.

The SQN1 actuator is widely used in industrial boilers, heating systems, furnaces, and other combustion equipment, where reliable and accurate damper positioning is required.

Technical Description

The Siemens SQN1 burner servomotor is an electromechanical actuator used to drive and position combustion air dampers or fuel valves in burner systems. The actuator converts control signals from burner controllers into rotational motion that adjusts the damper or valve position.

The device delivers rated torque up to approximately 1 Nm, which is suitable for lightweight damper control in compact burners.

Depending on the model, the actuator provides clockwise or counter-clockwise rotation to match different burner linkage configurations.

The running time for a 90° rotation can vary between 5 and 120 seconds, depending on the specific model and the burner management system used.
