Maxitrol KMR212G-2 Control Head Kit

The Maxitrol KMR212G-2 Control Head Kit provides a comprehensive field replacement solution for MR212G series modulating valves. Built as a direct replacement for the KT10447G, this 3-way control head is engineered specifically for direct-fired burners utilizing negative pressure (pull-through) applications. The kit includes the 3-way control head sub-assembly, a new top plate cover, and high-tolerance regulating diaphragm gaskets to ensure a gas-tight seal and precise pressure regulation during high-fire and low-fire cycles.

Designed for industrial environments, the KMR212G-2 handles gas flow modulation without the need for external motors or mechanical butterfly valves. By integrating the control head with the Selectra electronic gas flame modulation system, technicians can achieve instantaneous temperature control. The assembly is Made in the USA and supports natural, manufactured, mixed, and LP gases. Proper installation requires lining up the sensing holes in the gasket and flanges to maintain consistent negative pressure regulation across the burner's operating range.

• Full System Compatibility: Exact replacement for Maxitrol KT10447G and compatible with all MR212G series gas valves.
• Comprehensive Components: Includes the 3-way control head, top casting, and gaskets necessary for a complete modular rebuild.
• Negative Pressure Precision: Specifically optimized for pull-through burners, ensuring stable low-fire rates and reliable high-fire transitions.
• Industrial Durability: Robust construction designed for demanding HVACR applications with a temperature range of -40°F to 125°F.
• USA-Based Engineering: Precision manufactured for long-term service life in negative pressure direct-fired makeup air heaters.

Is the KMR212G-2 compatible with older MR212G valves?
Yes, this 3-way control head kit is the direct performance replacement for the KT10447G and is designed for the standard MR212G valve bodies found in most direct-fired equipment.

Does this kit include the regulating spring?
The kit typically includes a standard regulating spring (often pink for 2-5" w.c.); however, if your specific industrial application requires a different pressure range, the original spring from the removed head should be inspected and reused if it meets specification.

What is the difference between KMR212G-2 and KT10447G?
The KMR212G-2 is the current, complete kit that includes the top plate cover assembly, whereas earlier "KT" designations often referred to the head and gasket only without the full casting assembly.
