Siemens Building Technology 332-2973 Actuator
The Siemens 332-2973 Actuator is a rugged, No. 4 pneumatic damper actuator designed for reliable control of HVAC dampers and mixing box units. Engineered with a durable all-metal body and an ozone-resistant EPDM rolling diaphragm, this piston-type actuator provides consistent performance in demanding commercial environments. It features an 8-13 psi nominal spring range and a 4-inch stroke, making it the primary direct replacement for MCP-1140-1520 units. This model includes an RL 147 positioning relay to ensure precise damper positioning and a universal mounting kit that supports both fixed and pivot mounting configurations on extended shafts or frames. Whether you are retrofitting legacy pneumatic controls or installing new terminal units, the 332-2973 provides the mechanical thrust and gradual actuation required for accurate airflow management without the complexity of electronic components.
Key Benefits
- Direct Retrofit Compatibility: Serve as a drop-in replacement for MCP-1140-1520, minimizing field modification time.
- Integrated Positioning Relay: Facilitates accurate proportional control and repeatable damper blade positioning under varying load conditions.
- Versatile Mounting: The included universal mounting kit allows for pivot post or frame-mount installation, adapting to various duct and damper shaft layouts.
- Heavy-Duty Construction: Features a robust aluminum housing and a replaceable EPDM diaphragm for long-term service in air-handling systems.
- High Operational Thrust: Designed to drive mixing boxes and ventilating dampers effectively within an 8-13 psi spring range.
Common Questions
Is the 332-2973 compatible with older Barber Colman or Robertshaw systems?
Yes, this Siemens No. 4 actuator is frequently used to replace legacy pneumatic models like the MCP-1140-1520. Provided the 4-inch stroke and 8-13 psi range match your sequence, it integrates seamlessly into existing pneumatic control loops.
Can the diaphragm be serviced in the field?
Yes. The 332-2973 is designed with serviceability in mind. The EPDM rubber diaphragm can be replaced without removing the entire actuator body from the damper frame, reducing maintenance downtime.
What is the purpose of the included positioning relay?
The positioning relay ensures the actuator reaches the specific point in its 4-inch stroke dictated by the controller signal, regardless of damper friction or air velocity pressure against the blades.
