Siemens SQM50.461R1G3 Valve Actuator | 140 lb-in Torque, 25s Run Time
The Siemens SQM50.461R1G3 valve actuator is an electromotive reversing actuator from the SQM5 series. It has a 25-second running time for 90° rotation (CCW standard) and 140 lb-in torque. It places flow control valves, butterfly valves, and dampers very accurately using 4-20 mA input through the built-in AGA56.41G3 circuit board and is perfect for Siemens SQM50.461R1G3 valve actuator applications.
There is an outside position indicator, up to six switches that can be adjusted (limit, economy, auxiliary), auto/manual operation, and a shaft/cam drum that can be disconnected for quick setup. It has a die-cast aluminum housing (IP54), a synchronous motor, and 1000 Ohm potentiometer feedback.
It can be mounted in any direction and works reliably from -20°C to +60°C. This Siemens SQM50.461R1G3 valve actuator is great for managing burners, heating industrial spaces, and HVAC systems. It also improves safety, product quality, and performance in medium to large systems.

Advantages:
- For precise control in process applications, it has high modulating accuracy and low hysteresis.
- The auto/manual switch and forward/reverse toggle make it easy to set up and fix problems.
- Field-reversible rotation (CW/CCW) and clutches that can be disengaged for easy shaft/cam alignment.
- With different shaft options and adapter brackets, you can mount it in any position.
- For best performance, it has split-range capability, zero/span adjustment, and electronic linearization.
- UL, CSA, and CE-approved, and built to last so it can work reliably in harsh conditions.
Industry-Wide Application:
-> Modulation of air/gas dampers and fuel valves for oil and gas burners.
-> Industrial process heating necessitates ignition positioning and a high turndown.​
-> Boilers for commercial and industrial use that require precise flow control and dual-fuel configurations.​
-> HVAC systems that utilize dampers and butterfly valves.
-> Valve and rotary motion applications necessitate process control in manufacturing.
