Schneider Electric (Barber Colman) MPR-5610 Proportional Actuator

The Schneider Electric MPR-5610 is a high-torque, proportional hydraulic actuator engineered for precision modulation in commercial HVAC systems. This 120V spring return actuator is the industry-standard direct replacement for EA-81-11006, providing a seamless retrofit for legacy Barber Colman and Invensys installations. Designed to accept a 4 to 20 mA input signal, the MPR-5610 features an 82.5-ohm impedence and an oil-immersed motor for smooth, reliable operation on VB-7xxx series valves (1/2" to 2") or dampers when paired with appropriate linkages. Its fail-safe spring return mechanism ensures the valve or damper returns to its normal position immediately upon power loss, protecting critical equipment from temperature spikes or coil damage. Built with a die-cast lower housing and a NEMA 1 rating, this modulating valve actuator delivers 15 lb-in of torque, making it a rugged choice for building automation systems (BAS) and air handling units requiring consistent HVAC proportional control.

• Direct Retrofit Compatibility: Specifically designed to replace obsolete EA-81-11006 models without complex modifications.
• Precision Modulation: Responds accurately to 4-20 mA control signals for tight tolerance temperature and airflow management.
• Hydraulic Reliability: Features an oil-immersed motor and pump for quieter operation and extended field life in demanding environments.
• Field Adjustability: Includes an adjustable startpoint potentiometer, allowing technicians to calibrate the actuator stroke to specific system requirements.
• Fail-Safe Protection: Integration of a mechanical spring return ensures a predictable 46-second retract timing during power interruptions.

Is the MPR-5610 compatible with older Barber Colman valve bodies?
Yes, this actuator is a standard fit for 1/2" to 2" VB-7xxx series valves and can be used on many legacy valve bodies provided the correct AV-600 or AV-601 linkage is utilized.

Does this unit include the linkage for damper applications?
The MPR-5610 is a base commercial model. While it is fully capable of driving dampers, an AM-601 linkage must be ordered separately for damper mounting.

Can I use a 2-10 VDC signal with this actuator?
The MPR-5610 is natively designed for 4 to 20 mA proportional control. To use a voltage signal, a 500-ohm resistor (such as the AM-708) is typically required to convert the signal to the appropriate current range.
