Schneider Electric (Barber Colman) M573-2520 Actuator

The Schneider Electric M573-2520 is a heavy-duty pneumatic damper actuator designed for the precise positioning of air dampers in commercial HVAC control systems. This post-mounted actuator features a 3-inch stroke and a robust glass-filled nylon housing with a rolling neoprene diaphragm for reliable performance in demanding environments. Operable within a 3 to 12 psig spring range, it provides either proportional or two-position control, making it highly adaptable for multi-zone units, fan coils, and unit ventilators. The M573-2520 is industrially recognized as identical to the 2473-210, allowing for seamless field replacement or integration into Barber Colman pneumatic systems. Designed for line-of-sight installation with a 1/4" barbed fitting, it ensures stable torque and consistent airflow modulation across ventilating and mixing box applications.

• Interchangeable Design: Functionally identical to the 2473-210, ensuring a drop-in solution for legacy Barber Colman infrastructure.
• Industrial Construction: Features a corrosion-resistant glass-filled nylon body and a stainless steel shaft for long-term operational stability.
• Versatile Control: Supports both proportional and two-position signaling for variable air volume (VAV) and mixed-air applications.
• Reliable Spring Return: The 3-12 psi spring range is engineered to retract the actuator shaft automatically upon loss of supply air.
• Ease of Integration: Standard post-mount configuration with clevis and pin simplifies installation on dampers and inlet vanes.

Is the M573-2520 compatible with older Barber Colman pneumatic controls?
Yes, this unit is the direct manufacturer equivalent to the 2473-210 part number and fits the same pneumatic footprints commonly found in legacy systems.

What is the maximum supply air pressure for this actuator?
While the nominal operating pressure is 20 psig, the M573-2520 can withstand a maximum static air pressure of 30 psig.

Does this model include a positioner?
This specific model is a standard pneumatic piston actuator without a factory-installed positioner, though it is compatible with N800-0555 positioners if required for your sequence of operation.
