KMC Controls MCP-1040-5211 Actuator

The KMC Controls MCP-1040-5211 is a heavy-duty pneumatic damper actuator purpose-built for high-torque linear motion control in commercial HVAC systems. This 4-inch stroke pneumatic actuator is engineered to position automatic air dampers with precision, supporting both gradual and two-position applications. Featuring an 8-13 PSI spring range, the unit provides reliable thrust for large-scale dampers, ensuring consistent airflow regulation under varied static pressures. The MCP-1040-5211 includes a right-angle bracket mounting configuration and is supplied with a 1/2-inch crank arm for seamless integration into standard linkage setups.

For technicians managing complex air handling units, the MCP-1040 series offers a rugged black plastic body designed to withstand industrial environments while maintaining accurate positioning. Whether you are performing a field replacement or a new installation, this actuator's compatibility with diverse mounting posts and its ability to accept positive positioners make it a versatile choice for maintaining system balance. Its linear pneumatic motion ensures smooth operation on damper shafts, reducing mechanical wear and optimizing HVAC performance in critical building automation loops.

• Field Versatility: Designed for both gradual and two-position control of air dampers, facilitating adaptable airflow management.
• High Torque Output: The 4-inch stroke combined with a robust 8-13# spring range provides the mechanical force necessary for larger damper assemblies.
• Standardized Linkage: Equipped with a 1/2-inch crank arm and right-angle bracket for straightforward mounting and alignment with existing damper shafts.
• Industrial Durability: Constructed from high-grade materials to ensure long-term reliability in demanding mechanical room conditions.
• Upgrade Compatible: Can be outfitted with a positive positioner in the field for applications requiring enhanced control accuracy.

What is the primary application for the KMC MCP-1040-5211?
This actuator is specifically designed to position automatic air dampers within pneumatic control systems, commonly used for air handlers and large-scale ventilation units.

Does this model include a crank arm or bracket?
Yes, the MCP-1040-5211 comes standard with a right-angle bracket and a 1/2-inch crank arm for connection to the damper shaft.

Can the 8-13 PSI spring range be adjusted for different pressure spans?
While the internal spring is rated for 8-13 PSI, the unit can be used with a positive positioner and optional span springs (such as 5 or 10 PSI springs) to meet specific sequence-of-operation requirements.
