KMC Controls MCP-3631-3000 Actuator

The KMC Controls MCP-3631-3000 is an industrial-grade pneumatic rotary actuator engineered for precise proportional control of VAV terminal units and small dampers. This direct-coupled actuator features a factory-set 5 to 10 psi nominal spring range, allowing for predictable damper control in low-pressure pneumatic systems. Designed as the direct replacement for the legacy 35DP50000301 model, this unit ensures seamless mechanical compatibility during retrofits without extensive linkage adjustments. The "000" series designation confirms a 1/2-inch round shaft mounting interface, which can be adapted to 3/8-inch shafts using the HLO-1011 adapter. Its rugged design provides a high net force exertion of up to 42 lb at 0 psi, ensuring reliable performance in demanding commercial air distribution environments. Field-reversible mounting allows for both clockwise and counter-clockwise rotation, providing the flexibility required for complex cabinet internal layouts and ventilation system calibrations.

• Direct Interchangeability: Purpose-built to replace the 35DP50000301, reducing downtime during maintenance cycles.
• Broad Compatibility: Standard 1/2-inch diameter drive hub mounts directly to damper shafts; supports 3/8-inch shafts with additional adapters.
• Reliable Operation: Pneumatic pressure-driven mechanism provides smooth, modulating movement for precise airflow regulation.
• Installation Versatility: Dual-sided mounting capability enables simple field reversal of rotation direction.
• Robust Shaft Grip: Includes a standard non-rotation bracket and multiple drive hub locking options for secure, slip-free performance.

Is the MCP-3631-3000 compatible with square damper shafts?
The MCP-3631-3000 is optimized for 1/2-inch and 3/8-inch round shafts. For 3/8-inch square shaft applications, technical specifications recommend the MCP-3631-3001 variant.

What is the maximum supply pressure for this actuator?
This model is designed for standard pneumatic loops with an operating pressure range of 0 to 20 psi. Exceeding 30 psi may damage internal components.

Does this unit include the mounting hardware?
Yes, the actuator is typically supplied with a non-rotation bracket to facilitate secure mounting to the VAV terminal or damper housing.
