Siemens Building Technology 331-2961 Actuator
The Siemens 331-2961 is a high-performance No. 4 pneumatic damper actuator engineered for precise control in commercial HVAC systems. This rugged, metal-fabricated pneumatic piston actuator features a 4-inch stroke and is designed for the gradual or positive actuation of dampers in ventilating systems, mixing boxes, and air handling units. With a 8-13 psi spring range, it provides the necessary force for reliable operation in high-demand environments. The unit includes an integral pivot mount for versatile installation on extended shafts or frames and is equipped with a high-quality, ozone-resistant EPDM rolling diaphragm. Designed for technicians who need a durable solution for fire and smoke applications, this Powers Controls actuator is UL recognized and features a 1/8-inch NPT air connection with dual barb fittings for 1/4-inch OD tubing. Its heavy-duty construction ensures long-term stability even in systems requiring high effective diaphragm areas and extended travel.
Key Benefits- UL Recognized Performance: Built and tested for critical fire and smoke damper applications to ensure safety and code compliance.
- Enhanced Durability: Features an all-metal body construction and an ozone-resistant EPDM diaphragm for extended service life in harsh mechanical rooms.
- Precision Control: The 8-13 psi nominal spring range allows for accurate pneumatic damper control and easy sequencing with other pneumatic devices.
- Installation Versatility: The pivot mounting design accommodates various frame and shaft configurations, making it a go-to for field retrofits.
- Serviceability: Designed with a replaceable rolling diaphragm, allowing for field maintenance without replacing the entire damper actuator assembly.
What is the maximum air pressure for the Siemens 331-2961?
While the standard operating range is 8-13 psi, these actuators are typically rated for a maximum control pressure of 30 psi. Always verify your specific controller output to avoid exceeding the diaphragm limits.
Can this actuator be used in fire/smoke applications?
Yes, the 331-2961 is UL recognized for fire and smoke applications (category EMKU2), making it suitable for leakage-rated dampers and safety-critical ventilation systems.
Is the mounting hardware included with this model?
This specific model features an integral pivot mount. For universal mounting or bracket-specific installs, additional hardware like the 331-001 mounting plate may be required depending on the damper frame design.
