York S1-025-44125-000 Gas Valve

The York S1-025-44125-000 Gas Valve is a critical OEM replacement component designed for high-performance gas regulation in residential heating systems. Operating on a 24VAC coil voltage, this valve is engineered for precision, maintaining a factory-set 3.5" WC outlet pressure for natural gas while supporting up to 10" WC for specialized applications. This specific model features a 1/2" x 3/4" pipe size configuration, ensuring a secure fit and robust flow rate for mid-to-high capacity furnaces. As a direct cross-reference for the S1-025-38979-000, it offers a seamless drop-in solution for technicians servicing York, Coleman, and Luxaire equipment, specifically the DGAD060CDE model series. Built for durability in demanding environments, this NG/LP compatible gas valve utilizes a localized solenoid coil to provide immediate response to thermostat calls, ensuring safe ignition and consistent manifold pressure. Its compact design facilitates installation in tight burner compartments, while the rugged housing resists heat-induced fatigue, which is common in high-cycle residential units.

• Direct OEM Cross-Reference: Serves as the official replacement for legacy part numbers S1-025-38979-000, ensuring full mechanical and electrical compatibility.
• Dual Fuel Versatility: Field-adjustable and compatible with both Natural Gas (NG) and Liquid Propane (LP) systems across various pressure scales.
• Precision Pressure Regulation: Maintains stable 3.5" and 10" WC ratings to optimize burner efficiency and prevent over-firing or soot accumulation.
• Technician-Friendly Installation: Standard 1/2" NPT inlet and 3/4" NPT outlet connections allow for rapid manifold integration without extensive piping modifications.
• Reliable 24V Logic: Integrates perfectly with standard HVAC control boards, providing a definitive 24VAC signal response for safe furnace sequencing.

Is the S1-025-44125-000 compatible with my Coleman furnace?
Yes, this valve is a standard OEM part for many York-produced brands, including Coleman and Luxaire. Always verify your specific furnace model number against the manufacturer specifications to ensure the manifold porting and voltage match.

Can I use this gas valve for a propane conversion?
This valve is compatible with LP gas, but a conversion kit (including the correct spring and orifices) is required to safely transition from natural gas to propane. Adjusting the WC pressure to the manufacturer's specified LP setting is mandatory for safe operation.

What are the symptoms of a failing York gas valve?
Common indicators include the furnace clicking without the burners igniting, intermittent flame dropouts during a call for heat, or a 24V signal being present at the terminals without any gas flow through the 3.5" WC outlet.
