Siemens Building Technology 331-3012
The Siemens 331-3012 is a heavy-duty #6 pneumatic damper actuator designed for high-torque applications in commercial HVAC systems. This spring return actuator features a 4-inch stroke and a nominal 3-8 psi spring range, making it an ideal choice for the gradual or positive control of large dampers, centrifugal refrigeration inlet vanes, and fire/smoke dampers. Built with a rugged, metal-fabricated housing and a 17.9 sq. in. effective diaphragm area, this unit provides reliable thrust and precise positioning for outdoor air, exhaust, and multi-section dampers where 90-degree rotation is required.
Engineered for versatility, the 331-3012 includes an integral pivot and pivot post mounted on a fixed plate for extended shaft mounting. The package comes complete with a clevis and crank suitable for 3/8", 7/16", or 1/2" diameter shafts, facilitating a quick 28-minute field installation. The ozone-resistant silicone rubber diaphragm is fully replaceable, extending the operational life of the assembly. For systems requiring sequencing or high-capacity air handling, this No. 6 actuator delivers the mechanical force necessary for consistent HVAC performance.
Key Benefits:- Universal Shaft Compatibility: Included linkage and bracket support 3/8", 7/16", and 1/2" diameter damper shafts.
- High-Force Output: Large diaphragm area provides maximum thrust for multi-section and heavy-duty damper configurations.
- Industrial Durability: All-metal construction ensures stable operation within an ambient temperature range of -20 to 160°F.
- Precision Control: The 3-8 psi spring range allows for accurate sequencing with other pneumatic control devices and relays.
- Field Serviceable: The replaceable internal diaphragm permits maintenance without requiring full actuator replacement.
Can the 331-3012 be used on fire and smoke dampers?
Yes, the No. 6 pneumatic actuator is UL recognized for use on fire dampers and leakage-rated dampers, providing positive fail-safe operation via spring return.
Is this model compatible with positioning relays?
This specific part is designed for extended shaft mounting; however, it is compatible with the 147 series positioning relays if your application requires higher accuracy or faster response times.
What air connection does this actuator use?
The unit features a standard 1/8 inch NPT female air connection, suitable for common pneumatic tubing and fittings used in commercial building automation.
