KMC Controls MCP-0303 Actuator

The KMC Controls MCP-0303 is a heavy-duty, standard-body pneumatic damper actuator designed for the precise positioning of small to medium-sized dampers in HVAC air handling systems. This "bare" model features a 3-inch stroke and a 5 to 10 PSI operating spring range, making it a reliable choice for pneumatic control systems requiring linear motion. Constructed with a CRS body finished in zinc and dichromate, the MCP-0303 is built for durability in demanding mechanical environments, including ceiling plenum installations where non-metallic components are restricted.

For high-performance HVAC automation, the actuator utilizes a rugged neoprene diaphragm and bronze or Delrin bearings to ensure consistent operation across a wide temperature range of -20?? to 180??F. The 5/16" actuator shaft is nickel-plated to resist corrosion, providing a long-term solution for damper linkage applications. This 8 sq. inch effective area actuator delivers 34/67 in-lb of torque at 20 psi, ensuring reliable gradual or two-position control in professional air terminal units and ductwork installations.

• Pneumatic Reliability: The 5-10 PSI spring range offers predictable linear response for gradual control of HVAC dampers.
• Plenum Rated: All-metal body construction meets code requirements for installation in ceiling air spaces.
• Durable Materials: Features a high-strength neoprene diaphragm and nickel-plated shaft for increased service life in extreme temperatures.
• Compact Torque: Capable of managing up to 8 sq. ft. for gradual dampers or 10 sq. ft. for two-position dampers at 1000 fpm.
• Versatile Mounting: The bare actuator design allows for flexible integration into existing brackets or direct-coupled linkages.

• Does this model include mounting brackets or linkage? The MCP-0303 is a "bare" model, meaning it is the actuator only. Mounting brackets and linkage kits must be sourced separately based on your specific application.
• What is the maximum supply pressure for this unit? While the operating range is 0 to 20 psi, the maximum supply pressure is 30 psi. We recommend installing a tubing restraint if operating at maximum temperature and pressure.
• Is the diaphragm replaceable? Yes, the 3-inch replacement diaphragm for this series is typically the VTD-9423, allowing for field maintenance without replacing the entire housing.
