Maxitrol KMR212E-2 Control Head Kit

The Maxitrol KMR212E-2 is a specialized 3-way control head kit engineered specifically for Maxitrol MR212E modulation valves. As a critical component for maintaining precise pressure regulation in industrial and commercial combustion systems, this kit includes the modulating control head, a reinforced top plate cover assembly, and the necessary sealing gaskets to ensure a leak-proof installation. This Selectra modulation component allows for seamless interfacing between electronic controls and gas valves, facilitating accurate discharge air temperature control in make-up air handlers and high-efficiency furnace applications. Designed for heavy-duty cycling, the KMR212E-2 ensures mechanical stability and consistent feedback to the direct-fired burner controller. Professionals rely on this Maxitrol replacement part to restore system modulation linearity without replacing the entire valve body, significantly reducing downtime and maintenance costs during critical field repairs.

Key Benefits for Technicians:

• Precise Modulation: Provides accurate 3-way control for MR212E series valves, ensuring stable manifold pressure.
• Field Serviceable: Includes all required gaskets and the top plate assembly for a complete valves maintenance solution.
• Compatibility: Engineered to integrate directly with Selectra series electronics for reliable burner synchronization.
• Durable Construction: Built to withstand high-cycle operations in demanding HVACR environments.

Common Questions & Technical Considerations:

How do I verify if the KMR212E-2 is the correct kit for my valve?
Confirm that the main valve body is an MR212E. This kit is specifically designed for the 2-inch and larger series modulation valves and will not fit the smaller MR410 or MR510 series.

Can this control head be installed without disconnecting the main gas line?
Yes, the Maxitrol control head kit allows for top-side replacement. However, you must depressurize the system and ensure the gaskets are seated perfectly to prevent gas bypass or external leaks.

What signals drive the modulation on this control head?
It typically interfaces with a Maxitrol amplifier or controller that outputs the specific DC current required to actuate the 3-way head mechanism.
