York S1-4211700 Gas Valve

The York S1-4211700 Gas Valve is a critical OEM component designed for high-precision fuel regulation in residential and commercial York and Coleman heating systems. This 24-volt gas control valve is engineered to manage manifold pressure with exacting tolerances, ensuring stable combustion cycles and reliable ignition across various furnace platforms. Built for direct replacement compatibility with BGM and other flagship furnace series, it replaces older or failing gas controls to restore factory-spec manifold pressure (typically 3.5" W.C. for Natural Gas). This valve is primarily configured for Natural Gas but supports field conversion via a propane kit for flexible application across different fuel types.

For service technicians, this unit offers simplified 1/2" NPT inlet/outlet connections and standard spade terminals for quick integration into the existing wiring harness. As a genuine York replacement part, it guarantees the correct flow rate and internal safety shut-off timing required to maintain heat exchanger integrity and overall system safety. Whether you are dealing with a lockout condition or inconsistent pilot proving, this valve is the industry-standard solution for restoring HVAC system performance without modifications to the burner assembly.

• OEM Compatibility: Specifically calibrated for York, Coleman, and Luxaire gas furnaces, ensuring a seamless fit and electrical alignment.
• Reliable Gas Regulation: Maintains consistent manifold pressure to prevent soot buildup and ensure efficient burner operation.
• Durable Solenoid Construction: Robust internal coils designed to withstand high-cycling demands in harsh mechanical room environments.
• Standardized Connections: Features universal 1/2-inch piping ports for straightforward installation on most residential manifold rails.

Common Questions:

Is the York S1-4211700 compatible with Propane (LP)?
Yes, while this valve is factory-set for natural gas, it can be converted for Liquid Propane applications using the appropriate manufacturer-approved conversion kit. Always verify manifold pressure with a manometer after conversion.

Can I use this to replace a different brand of gas valve?
This part is a specific OEM replacement for York and associated brands. Utilizing this valve on non-compatible brands is not recommended, as orifice sizes and voltage requirements vary by manufacturer.

What are the symptoms of a failing gas valve?
Common indicators include the furnace failing to light despite a proven igniter, intermittent "no flame" lockouts, or unusual clicking noises from the solenoid during the ignition sequence.
