Maxitrol KMR212D-2 Control Head Kit

As a veteran technician, you know that maintaining the integrity of Maxitrol Selectra systems requires precise components that handle both modulation and pressure regulation without mechanical lag. The Maxitrol KMR212D-2 Control Head Kit is the professional-grade solution for servicing MR212D series modulating valves. This 3-way control head is engineered to provide infinite, non-fluctuating temperature control by managing fluid flow through the regulator's top casting. The kit includes the 3-way control head sub-assembly, a top plate cover assembly, and the necessary gaskets to ensure a leak-proof seal during field replacement. It serves as the direct replacement for KT10447D, offering a more comprehensive assembly for faster uptime. Designed for industrial automation and high-capacity HVACR systems, it excels in direct-fired atmospheric burner applications where consistent manifold pressure is critical. By replacing a worn head with this genuine Maxitrol part, you restore the modulator-regulator's ability to respond instantaneously to Selectra series amplifiers, maintaining stable discharge temperatures across various heat loads.

• System Compatibility: Engineered specifically for MR212D gas modulating valves to restore factory-spec flame adjustment.
• Direct Crossover: Seamlessly replaces the obsolete KT10447D, ensuring current HVACR technical specifications are met.
• Complete Service Kit: Includes the top cover assembly and gaskets, eliminating the need to source individual seals for a standard rebuild.
• High-Performance Regulation: Maintains precise 3-way fluid flow control for consistent burner performance in industrial process heating.
• Rugged Construction: Built to withstand the environmental demands of mechanical rooms and industrial air handlers.

Is this compatible with MR212E or G versions? No, this kit is specifically calibrated for the MR212D. While they look similar, the KMR212D-2 is sized for the flow characteristics and sensing requirements of the D-series body. Use KMR212E-2 or KMR212G-2 for larger valve bodies.

Does this kit include the high-fire spring? Standard Maxitrol control head kits typically include the necessary regulating diaphragm gasket and the head assembly; however, technicians should always inspect the high-fire spring during teardown and reuse it if it meets tension specs, as it is calibrated to the specific manifold requirements.

Can this be used for 2-speed blower applications? Yes, the KMR212D-2 is designed for MR212D-2 valves, which are the industry standard for dual fuel or 2-speed blower operation in industrial heaters.
