High Torque Actuator 120V AC Operation 15 Nm Torque 90° Rotation Industrial Burner Control Robust Design

Product description

The Siemens SQN75.664A26 is a powerful electromechanical actuator designed for heavy-duty applications in industrial and commercial boiler and burner management systems. Operating on 120V AC (50/60 Hz), it delivers a robust 15 Nm of torque through a 90° rotation, capable of actuating larger or stiffer gas valves and air dampers.

This actuator is crucial for applications requiring higher torque to ensure reliable positioning of fuel and air control elements. It is commonly found in large industrial boilers, process heaters, and other high-demand combustion systems where precise and forceful control is paramount for safety and efficiency.

Stanlo Automation, a veteran-owned surplus parts distributor, stocks the Siemens SQN75.664A26. We provide reliable access to specialized automation components, helping industries maintain peak performance with quality surplus parts.
