Siemens damper motors, servo motors Actuators are highly versatile modulating motors actuators used for the positioning of flow control valves, butterfly valves, dampers, or any application requiring rotary motion. The reversible actuators of the SQM... range are for use in connection with controllers or switching devices equipped with changeover contacts. The SQN...SQM… Servo Motors are designed for driving gas or air dampers of oil or gas burners of small to medium capacity or for load-dependent control of the fuel or combustion air volume. Various Models are available with different stroke, timings & torque.

SQN3…SQN4... SQN7... SQN9... SQM10..SQM20... SQM45…SQM48... SQM5... AGA56... ASZ...

SQN3…SQN4... The Damper Motors SQN3/SQN4…are designed for driving gas or air dampers of oil or gas burners of small to medium capacity, or load dependent control of the fuel or combustion air volume. Many Servo Motors Varients are available.             SQN7... The SQN7 actuators are designed for driving gas or air dampers of small to medium capacity for load dependent control of the fuel and combustion air volume in connection with 1 or 2 wire control or 3 position controllers.             SQN9... The SQN9..actuators are designed for driving gas or air dampers of oil or gas burners of small to medium capacity, for load-dependent control of the fuel and combustion air volume.             SQM10..SQM20... The reversible actuators of the SQM…range are for use in connection with controllers or switching devices equipped with changeover contacts.             SQM45…SQM48... The actuators of the SQM45/SQM48 are used to drive gas dampers, air dampers, oil control valves and other ancillary equipment. When used in connection with burner controls the associated controlling elements are controlled depending on burner control.             SQM5... The SQM5….actuators are used to drive air or gas burners of medium to large capacity. They are used primarily for load-dependent control of gas,oil and combustion air.             AGA56... Analog input modules for the control of SQM5..air damper actuators by continuous analog control signal, such as 4..20 mA and continuous analog position feedback             ASZ... For integration into SQM..and SQN…..actuators to indicate the position of the actuators drive shaft. They can be used for both position indication and position feedback.
