Siemens Building Technology 331-4825 Actuator
The Siemens 331-4825 is a rugged, metal-fabricated No. 3 Pneumatic Actuator engineered for reliable performance in demanding commercial HVAC environments. Designed for the precise modulation of air valves and dampers, this unit features a 8-13 psi nominal spring range and a versatile 2-3/4 inch stroke. Built with an all-metal body and an ozone-resistant rubber rolling diaphragm, it provides consistent force for both two-position and modulating applications, including UL-rated fire and smoke leakage dampers.
For the contractor in the field, the 331-4825 is a preferred solution for unit ventilators, air handlers, and terminal boxes. Its modular design and threaded shaft simplify the installation of various linkage kits and accessories, ensuring compatibility with a wide range of hardware. The enclosed construction protects internal components from debris, maintaining operational integrity in plenum or mechanical room settings. When pneumatic damper control requires a high-thrust, lightweight actuator with a proven service history, this Siemens actuator delivers the necessary 11-inch-pound torque equivalents and linear movement to keep systems balanced and code-compliant.
Key Benefits- All-Metal Construction: Durable aluminum housing and plated steel stem resist impact and environmental wear in mechanical rooms.
- Precise Graduation: The 8-13 psi spring range allows for accurate sequencing and responsive control of HVAC dampers.
- Extended Stroke Capability: A full 2-3/4 inch stroke provides the travel necessary for larger air valves and complex multi-blade damper assemblies.
- Application Versatility: Ideal for unit conditioners and branch duct control where space and reliability are critical factors.
- Code Compliance: Designed to meet technical requirements for fire and smoke leakage rated damper actuation.
Is the 331-4825 compatible with different mounting styles?
Yes, while this model is typically used for fixed mounting, its modular design supports pivot mounting and is compatible with a variety of Siemens linkage kits and mounting brackets for flexible field installation.
What is the maximum air pressure for this pneumatic actuator?
The unit is rated for a maximum operating air pressure of 25 psig, ensuring it can handle standard pneumatic control system spikes without diaphragm failure.
Can I use a positioning relay with this model?
The No. 3 actuator family supports the addition of a positioning relay as an optional accessory to improve speed and accuracy in long pneumatic tubing runs.
