SQN30.111A2700 – Siemens Actuator

Actuators

Electromotoric actuators for air dampers or for fuel / air ratio control with oil or gas burners of small to medium capacity.

Use

The actuators are used primarily for controlling the amount of combustion air:

– Load-dependent in connection with P-PI or PID controllers, such as the RWF40…

– Directly with the help of the different types of burner controls, such as the LOA…, LMO…, LMG… or LFL…
