KMC Controls MCP-3631-5000 Actuator

The KMC Controls MCP-3631-5000 is a high-performance direct coupled rotary pneumatic actuator engineered for precise control of VAV terminal units and small damper applications. Operating within an 8-13 PSI spring range, this unit provides reliable residential and commercial airflow regulation. The "000" series design features a versatile drive hub that mounts directly to 1/2-inch diameter damper shafts, and with the HLO-1011 adapter, it is fully compatible with 3/8-inch shafts. This flexibility, combined with the ability to mount on either side for clockwise or counterclockwise rotation, ensures a seamless fit for various field configurations. This pneumatic damper actuator utilizes a robust internal mechanism to deliver consistent torque, maintaining system pressure and improving overall energy efficiency across the HVAC control system. Built by KMC Controls, a leader in building automation, the MCP-3631-5000 is a standard-issue component for technicians requiring dependable, zero-maintenance rotary motion in low-pressure pneumatic circuits.

Key Benefits

• Universal Shaft Compatibility: Native support for 1/2-inch round shafts with easy adaptation for 3/8-inch round or square shafts using standard KMC hardware.
• Field-Reversible Rotation: Simplifies installation by allowing the rotary actuator to be mounted for either clockwise or counterclockwise action without additional parts.
• Precise VAV Control: Specifically calibrated for an 8-13 PSI pressure range, ensuring accurate positioning for small dampers and air terminal units.
• Durable Pneumatic Design: Features a non-rotation bracket and a robust drive hub to prevent backlash and ensure long-term mechanical stability in variable air volume systems.

Common Questions

What shaft sizes does the MCP-3631-5000 support?
Out of the box, it fits 1/2-inch diameter shafts. By utilizing the HLO-1011 shaft adapter, you can also mount it to 3/8-inch diameter or 3/8-inch square shafts commonly found in legacy VAV units.

Can the rotation direction be adjusted in the field?
Yes. The actuator is designed for "side-swapping," meaning you can mount either side towards the damper to achieve the required rotation direction for your specific damper blade configuration.

Is this model suitable for high-pressure systems?
This specific model is calibrated for 8-13 PSI. For systems requiring different start/stop pressures or higher torque for large dampers, verify the pneumatic signal range of your controller before installation.
