Siemens Building Technology 331-3011 Actuator
The Siemens 331-3011 is a high-performance No. 6 pneumatic damper actuator designed for heavy-duty HVACR applications requiring high torque and precise control. This spring-return pneumatic actuator features a rugged metal-fabricated body and is UL recognized for use on fire dampers and leakage-rated dampers, ensuring reliability in critical air-handling systems. With a nominal 8-13 psi spring range and a standard 4-inch stroke, it provides gradual or positive actuation for large dampers, centrifugal refrigeration inlet vanes, and fan discharge systems. The integrated rolling diaphragm is constructed from ozone-resistant silicone rubber, allowing for a 17.9 sq. in. effective area and long-term service life in demanding environments. This specific kit includes the essential mounting bracket and linkage hardware, facilitating universal installation for extended shaft or frame mounting on 3/8", 7/16", or 1/2" diameter shafts. Technicians can further enhance performance by adding an optional positioning relay or forward travel stops to meet specific sequence-of-operation requirements.
Key Benefits of the Siemens 331-3011 Actuator:- Universal Mounting Flexibility: Includes mounting plate, clevis, and crank for seamless installation on extended shafts or damper frames.
- High-Torque Performance: The No. 6 design offers a large diaphragm area (17.9 in²) to drive oversized dampers and inlet vanes.
- Fire and Smoke Safety: UL recognized (EMKU2) for integration into leakage-rated and fire damper assemblies.
- Durable Construction: Features an all-metal housing and a replaceable silicone rubber diaphragm to withstand industrial environments.
- Field Serviceable: The diaphragm and linkage components are designed for straightforward replacement to minimize system downtime.
Is the 331-3011 compatible with 1/4" tubing?
Yes, the 1/8" NPT internal thread air connection is designed to accept standard barb fittings for 1/4" O.D. plastic or copper tubing.
Can this actuator be used for sequencing?
The 8-13 psi spring range is ideal for sequencing with other pneumatic devices, and the unit supports the addition of a positioning relay for more complex control logic.
What is included in the bracket and linkage assembly?
This model comes with the universal mounting plate, pivot post, clevis, and crank arms required for most shaft diameters up to 1/2".
