Honeywell SV9641M4510 Gas Valve

The Honeywell SV9641M4510 SmartValve is a high-capacity, intermittent hot surface pilot ignition control designed for modern fan-assisted combustion systems. As a heavy-duty gas furnace valve, it integrates electronic pilot sequencing and gas flow control into a single, compact unit. This 24V gas valve features a 3/4" x 3/4" NPT connection and comes with an LP conversion kit and two 3/4" x 1/2" reducer bushings to ensure maximum job site flexibility. Engineered for reliability in demanding environments, it operates within an ambient temperature range of -40°F to 175°F and includes a 90-second ignition trial time with continuous retry logic. Whether you are performing a Honeywell SmartValve troubleshooting task or a full system upgrade, this unit serves as the SV9541M2094 replacement and is compatible with various Heil, Tempstar, and commercial cooking applications. Its standard opening characteristics and 3.5" w.c. regulator setting provide stable manifold pressure for consistent burner performance.

Key Benefits

• Universal Compatibility: Serves as a direct replacement for SV9540M2229, SV9541M2094, and SV9640M4132, reducing inventory needs for service trucks.
• Integrated Ignition Control: Combines gas flow safety with electronic intermittent pilot sequencing, eliminating the need for a separate ignition module.
• Field Adaptability: The included LP gas conversion kit and reducer bushings allow for seamless transition between natural gas and propane systems.
• Robust Performance: Designed for fan-assisted appliances with a 15-second prepurge and 30-second postpurge sequence to ensure clean combustion cycles.
• Accurate Diagnostics: Features 1/8" NPT pressure tappings for precise inlet and outlet pressure measurements during commissioning.

Common Questions Is the SV9641M4510 compatible with older SmartValve versions? Yes, it is the designated updated replacement for the SV9541 series. However, always verify your wiring harness (typically 2x2 or 4x4) and terminal board requirements, especially when interfacing with power-stealing thermostats. How do I handle a "no-light" condition during the 90-second trial? This valve utilizes a continuous retry sequence. If ignition fails, ensure the 24VAC transformer is rated for at least 50 VA and check the 3µA flame rectification signal. The valve will enter a five-minute delay before attempting a new ignition sequence. Can this valve be mounted in any orientation? The Honeywell SV9641M4510 can be mounted from 0 to 90 degrees in any direction from the upright position of the gas control knob, including vertical orientations, provided the flow follows the direction of the arrow.
