The SQN3/ SQN4 actuators 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:
• In connection with P-PI or PID controllers,
such as the RWF40
• Directly via the different types of burner
controls, such as LOA, LMO, LMG or LFL
• In connection with 1- or 2-wire control or
3-position controllers
