Siemens Building Technology 331-4824 Actuator
The Siemens 331-4824 is a #3 pneumatic damper actuator engineered for proportional control in medium-duty HVAC applications. Operating within a spring range of 8 to 13 psi, this unit provides a reliable 2-3/4 inch stroke, making it a standard solution for terminal units, small-to-medium dampers, and mixing boxes. Built with a rugged aluminum housing and a durable internal diaphragm, this direct-acting actuator ensures consistent positioning even in demanding environments. For field versatility, this model features a pivot mounting configuration and is compatible with standard 1/8" NPT air connections. Properly calibrated, the 331-4824 maintains precise air volume control, reducing hunting in pneumatic control loops and ensuring regional dampers respond accurately to pilot positioner or thermostat signals. Whether you are performing a legacy retrofit or maintaining a commercial air handling unit, this Siemens pneumatic actuator provides the mechanical force and long-cycle reliability required by professional mechanical contractors.
Key Benefits for Field Installation
- Precise 8-13 PSI Spring Range: Optimized for standard pneumatic control systems requiring accurate proportional response.
- Compact #3 Footprint: Designed for easy installation in tight mechanical spaces and terminal box enclosures.
- Robust Construction: Features a resilient diaphragm and high-quality internal components for high-cycle industrial use.
- Standard 2-3/4" Stroke: Provides the necessary travel for a wide range of damper blade configurations and linkage setups.
Common Technical Questions
What is the maximum air pressure for the Siemens 331-4824?
This actuator is typically rated for a maximum control signal pressure of 30 psi, though it operates primarily within the 8 to 13 psi spring range for standard modulation.
Can this actuator be mounted in any orientation?
Yes, the pivot mounting and versatile design allow for flexible installation, provided the linkage remains clear of obstructions and aligned with the damper shaft.
Is the diaphragm replaceable on this model?
Yes, the Siemens #3 series is designed for serviceability, allowing for diaphragm replacement to extend the service life of the actuator body.
