The Maxon 41637 is a heavy-duty, industrial-grade 6-second operator assembly designed specifically for the Maxon Series 21500 electro-mechanical gas valve. Engineered for precise burner system control, this actuator provides the necessary motorized force to manage fuel shut-off and flow regulation in high-demand environments such as industrial boilers, kilns, and multi-stage furnaces. Operating on 115 VAC at 50/60 Hz, the 41637 ensures a consistent 6-second opening timing, critical for meeting specific safety interlocking circuit requirements and purging sequences in complex combustion systems. Built for long-cycle reliability, the Maxon 41637 operator features a rugged construction that interfaces seamlessly with the Series 21500 valve body. This assembly is a direct Honeywell Maxon replacement part, facilitating rapid field installation and minimizing downtime during maintenance. Its electro-mechanical design provides a fast-acting safety return, ensuring fuel lines are secured instantly upon power loss. For technicians managing industrial combustion equipment, the 41637 offers a reliable solution for maintaining ANSI/FCI 70-2 Class VI seat leakage standards and overall system integrity. Key Benefits Optimized Timing: Fixed 6-second motor timing provides predictable opening speeds for precise fuel management and safety sequencing. High Compatibility: Purpose-built for the Series 21500, ensuring exact mechanical alignment and torque specifications. Industrial Durability: Designed for heavy cycling in harsh environments, maintaining performance across a wide ambient temperature range. Safety Integration: Features internal terminal blocks for easy wiring into flame safeguard and limit control strings. Common Questions What is the primary function of the Maxon 41637? It serves as the motorized actuator for the 21500 series valve, converting electrical signals into mechanical motion to open or close the fuel line within a 6-second window. Can I use a 2.5-second operator in place of the 6-second 41637? No. Valve timing is critical for burner sequencing and safety code compliance. Always match the timing specified by the original system design. Does this operator require field lubrication? The internal gear train and motor components are factory-sealed and typically do not require field lubrication during their service life. This item is not eligible for free shipping.
