Siemens Building Technology 331-2930 Actuator
The Siemens Building Technology 331-2930 Actuator is a heavy-duty, metal-fabricated No. 4 pneumatic damper actuator designed for reliable control of HVAC systems. This pneumatic piston-type actuator features an integral pivot mount and 4-inch stroke, providing the linear force necessary for the gradual or positive actuation of outdoor air dampers, mixing boxes, and fire/smoke dampers. With a 3-13 psi spring range, this unit is engineered for precision sequencing with other pneumatic control devices in high-demand environments.
As a veteran's choice for ventilating system control, the 331-2930 utilizes an ozone-resistant EPDM rubber diaphragm that is fully replaceable, extending the service life of the damper mounting accessory. The rugged construction ensures stable performance in unit ventilators and static pressure control applications. The air connection uses 1/8" NPT female threads with a dual barb elbow fitting designed for 1/4" OD tubing, facilitating a secure integration into existing pneumatic lines.
Key Benefits- High Torque Output: Heavy-duty metal body provides the mechanical advantage required for large damper sections.
- Versatile Mounting: Includes clevis and clevis pin specifically for frame or internal pivot mounting configurations.
- Serviceable Design: Features a replaceable rolling diaphragm to maintain peak pneumatic response without replacing the entire housing.
- Broad Application: Ideal for fan discharge, return air, and exhaust damper control in commercial HVACR settings.
What is the effective stroke length for the 331-2930?
This model provides a fixed 4-inch stroke, making it suitable for standard linkage and damper arm reaches found in global HVAC systems.
Can I use this for fire and smoke damper applications?
Yes, the rugged metal fabrication and positive actuation characteristics make it a reliable component for fire/smoke damper safety protocols.
What is the standard pneumatic connection size?
It utilizes a 1/8" NPT internal thread and typically ships with a 1/4" OD tube barb fitting for standard field tubing installations.
