Resideo SV9501M8129 Valve
The Resideo SV9501M8129 is a technical-grade intermittent pilot gas valve designed for sub-atmospheric and atmospheric gas-fired heating applications. This SmartValve system control integrates electronic sequencing, pilot flame sensing, and main gas control into a single modular footprint, streamlining the replacement of legacy Honeywell SV9500M8667 and SV9501M8129/U units. This specific 24Vac valve is a fast-opening gas valve with a 90-second ignition trial time and continuous retry logic, ensuring reliable ignition cycles in high-demand residential and light commercial environments. It features a standard 1/2" x 1/2" NPT body pattern, a 1/2 psi pressure rating, and an integrated 1/8" pressure tapping for precise manifold adjustments. Rated for extreme ambient temperatures from -40°F to 175°F, this hardware is engineered for durability in unconditioned mechanical rooms. Designed for natural gas service (LP conversion capable with appropriate kits), it facilitates direct synchronization with Q3450 or Q3480 pilot burners, eliminating the need for complex prepurge cycles or separate ignition modules.
Key Benefits:
- Direct Replacement: Simplifies service calls by replacing SV9500M8667 and SV9501M8129/U without cabinet modifications.
- Integrated Sequencing: Combines electronic intermittent pilot sequencing and flow control to reduce point-of-failure risks in the heating circuit.
- High Compatibility: Fits a broad range of furnace gas valve replacement scenarios including boilers, unit heaters, and rooftop furnaces.
- Robust Environmental Tolerance: Operates efficiently across a wide thermal spectrum, maintaining 3.4" w.c. regulation in cold-start conditions.
- Streamlined Installation: Features a straight-through body design and standard NPT threading for rapid field deployment.
Common Questions:
Does this valve require a separate ignition module?
No, the Resideo SV9501M8129 is a SmartValve, meaning the ignition control and sequencing logic are built directly into the valve body.
Which pilot burners are compatible with this gas valve?
This unit is designed for use with intermittent pilot ignition systems and is specifically compatible with Resideo Q3450 and Q3480 pilot burner assemblies.
Can this natural gas valve be used for Propane (LP) applications?
The SV9501M8129 is factory-set for natural gas but can be converted for LP using a manufacturer-approved conversion kit. Always verify manifold pressure after conversion.
