Maxitrol KT10460 Tube

The Maxitrol KT10460 is a specialized by-pass tube engineered specifically for the MR212G modulating gas valve. For veteran technicians managing direct-fired burners and negative pressure systems (pull-through applications), this OEM component is critical for maintaining a stable minimum firing rate. When the main valve is closed, the KT10460 bypass tube ensures a consistent low fire to the heater, preventing flame instability during the modulating cycle. This tube is designed to handle the rigorous demands of industrial gas pressure regulators, supporting non-fluctuating temperature control in Selectra electronic gas flame modulation systems. Utilizing genuine Maxitrol replacement parts ensures that the bypass flow remains accurately calibrated to the factory-set or field-adjusted negative pressure requirements, ranging from -1.5” w.c. to -3.5” w.c. Integrating this specific by-pass tube for MR212G ensures seamless compatibility and restores the high-precision performance of your negative pressure regulator without the risk of pneumatic leaks or inconsistent combustion.

• Precision Bypass Control: Maintains a reliable minimum firing rate for consistent burner performance during low-load conditions.
• Direct-Fired System Support: Optimized for negative pressure applications inside make-up air units and process heaters.
• OEM Compatibility: Exact fit for the Maxitrol MR212G series, eliminating the need for field modifications or generic fittings.
• Enhanced Combustion Stability: Prevents hunting and flame-outs by ensuring steady gas flow through the bypass circuit.
• Durable Construction: Engineered to withstand the inlet pressures and environmental conditions typical of industrial HVACR environments.

How do I confirm if the KT10460 is the correct tube for my valve?
Verify the model number on your gas valve body. This specific tube is designated for the G-sized MR212 (typically 2-1/2" or 3" NPT models). For D, E, or J series valves, a different kit number (e.g., KT10453) is required.

Does this kit include gaskets for the bypass connection?
While this part focuses on the by-pass tube itself, many technicians recommend checking the status of the seals at the 3-way control head during installation to ensure a gas-tight fit.

Can this tube be used on positive pressure (push-through) systems?
No, this component is designed for negative pressure pull-through systems. For push-through applications (suffix -1), consult the specific parts manual for the appropriate positive pressure bypass configuration.
