Product Overview

The Siemens SQM33 series burner servomotors are high-precision actuators designed to control and position air dampers, gas valves, and oil control valves in oil and gas burner systems. These actuators regulate combustion components according to the burner load to maintain stable and efficient burner operation.

The SQM33 series is commonly used with Siemens electronic fuel-air ratio control systems and burner management systems such as LMV2 and LMV3, allowing advanced modulation and accurate control of combustion processes.

Unlike traditional actuators with mechanical cams, the SQM33 series is typically electronically controlled through the burner management system, which manages actuator positioning with high precision.

These actuators are compact, high-speed units designed for industrial burners, boilers, furnaces, and process heating systems, where precise positioning and reliable performance are required.

Technical Description

The Siemens SQM33 burner servomotor is an electronic actuator used to drive and position air dampers and fuel control valves in industrial combustion systems. The actuator operates according to signals from the burner management system, allowing precise control of combustion parameters.

The SQM33 uses high-precision electronic control and stepper motor technology, enabling accurate positioning without mechanical cam adjustments.

The actuator can deliver rated torque between approximately 1.2 Nm and 3 Nm, depending on the model, making it suitable for compact industrial burner systems.

It typically operates with 24 V control voltage and supports integration with Siemens combustion management systems for fully automated burner operation.
