KMC Controls MCP-1040-2211 Actuator

For technicians and facility managers maintaining legacy systems, the KMC Controls MCP-1040-2211 Actuator is a critical pneumatic damper actuator engineered for precise positioning of automatic air dampers. This robust unit features a 4-inch stroke and a 3 to 12 psi spring range, allowing for gradual or two-position control in demanding air-handling environments. Designed to provide a reliable HVAC actuator replacement, the MCP-1040-2211 is a 100% identical cross-reference for the Barber Colman M574-2211 and the 2474-110. Its right-angle mounting configuration and 1/2-inch C-arm (crank arm) facilitate seamless integration into existing control linkages, ensuring the mechanical advantage needed for effective airflow regulation. Built by KMC Controls, this 4x4 series actuator utilizes an 11-square-inch effective diaphragm area to deliver consistent force, resisting the binding common in older ventilation systems. When you need a drop-in solution to restore commercial HVAC system performance without re-piping or modifying brackets, this proportional pneumatic controller is the industry standard for damper shaft control.

Key Benefits

• Precision Performance: The 3-12 psi operating range provides stable proportional control for accurate damper modulation.
• Heavy-Duty Linkage: Equipped with a 1/2" C-arm for secure attachment to standard damper shafts and linkages.
• Versatile Application: Suitable for both gradual modulation and standard two-position air damper applications.
• Industrial Reliability: Rugged construction designed specifically for the high-cycle demands of commercial air handling units.

Common Questions

Is the MCP-1040-2211 compatible with existing Barber Colman hardware?
Yes, this model is the direct, identical successor to the M574-2211 and 2474-110. It utilizes the same mounting footprint and mechanical specifications for an easy swap.

What is the effective area of this actuator?
The MCP-1040 series features an 11-square-inch effective diaphragm area, ensuring reliable torque and stroke power across its 4-inch travel range.

Can this be used for two-position control?
While often used for proportional modulation, it is fully capable of two-position (on/off) applications within a pneumatic control circuit.
