The Siemens SQM9 series burner servomotors are heavy-duty actuators used to drive air dampers, butterfly valves, and oil pressure controllers in industrial combustion systems. These actuators regulate the supply of combustion air, gas flow, and oil volume according to burner load conditions to maintain efficient and stable burner operation.

The SQM9 servomotors are mainly used in medium- to large-capacity oil and gas burners and thermal process plants, where high torque and precise modulation are required.

These actuators are typically integrated with Siemens electronic fuel-air ratio control systems such as LMV5 or LMV6, enabling automatic control of combustion parameters during burner operation.

The SQM9 series features robust mechanical construction, high torque output, and precise rotational control, making it suitable for industrial boilers, furnaces, and other high-capacity combustion equipment.

Technical Description

The Siemens SQM9 burner servomotor is an electromechanical actuator used to control the position of air dampers and fuel valves in industrial burner systems. The actuator receives control signals from a burner management system and converts them into rotary motion to adjust the airflow or fuel supply.

These actuators provide torque up to approximately 60 Nm, making them suitable for large dampers and valves used in high-capacity industrial burners.

The actuator’s running time typically ranges from about 30 to 120 seconds, depending on the configuration and burner control system used.

The SQM9 series is commonly used with electronic ratio control systems such as Siemens LMV5 and LMV6, which automatically regulate combustion air and fuel flow for efficient burner operation.
