KMC Controls MCP-3631-8000 Actuator

The KMC Controls MCP-3631-8000 is an industrial-grade pneumatic rotary actuator designed for the precise control of VAV terminal units and small damper systems. Built for heavy-duty HVACR environments, this model features a 3-8 PSI spring range and provides fixed power for consistent damper positioning. Its direct-coupled design allows for an efficient transfer of torque, mounting directly onto 1/2-inch round shafts or 3/8-inch shafts with an adapter. With an IP66/NEMA 4 enclosure, this unit is engineered to withstand moisture and airborne contaminants common in mechanical rooms. This KMC pneumatic damper actuator supports both clockwise and counterclockwise rotation, offering the versatility required for various air-side applications. Veteran technicians rely on the MCP-3631 series for its robust internal diaphragm and non-rotation bracket, ensuring a stable, drift-free operation in high-performance building automation systems.

• Universal Compatibility: Mounts directly to 1/2-inch round shafts; compatible with 3/8-inch round or square shafts using standard adapters.
• Field-Reversible Rotation: Simplifies installation by allowing either side of the rotary actuator to face the damper for CW or CCW motion.
• Harsh Environment Protection: Features a rugged NEMA 4/IP66 enclosure to protect internal components from dust and water spray.
• Precise VAV Control: Engineered specifically for VAV terminal units, providing 25 lbs of force to ensure accurate air volume regulation.

What is the operating pressure for the MCP-3631-8000?
This model operates within a nominal 3 to 8 PSI spring range, making it ideal for standard pneumatic control systems.

Can I use this actuator on square damper shafts?
The MCP-3631-8000 is designed for round shafts. For 3/8-inch square shafts, the MCP-3631-8001 model is typically recommended, though adapters may be used for round-to-square transitions.

Does this unit include a positioner?
No, this is a fixed-power pneumatic rotary actuator. If your application requires a built-in positioner, you should verify the specific series requirements for your control loop.
