York S1-025-44124-000 Gas Valve

Ensure reliable furnace operation and precise combustion control with the York S1-025-44124-000 Gas Valve. This HVAC 2-stage gas valve is a direct replacement for 025-38915-000 and 025-35394-000, specifically engineered for York residential furnaces and compatible Coleman or Luxaire systems. Operating at 24V, this slow-open gas valve features a J-Style configuration designed to manage staged fuel delivery, significantly reducing ignition noise while maintaining stable manifold pressures. With a 3/4 inch x 1.6 inch gas connection and factory settings of 3.5" WC and 1.6" WC for high and low fire, it delivers accurate regulation for natural gas systems. This furnace gas valve replacement is essential for technicians performing HVAC gas valve troubleshooting, ensuring that the unit responds correctly to thermostat staging demands. As an OEM York heating part, it provides the precise bypass porting and solenoid coil resistance required for integration with modern control boards, preventing nuisance flame outages and pressure switch trips.

• Optimized Staging: The two-stage gas valve design ensures smooth transition between high and low heating cycles for improved furnace efficiency.
• Direct Compatibility: Explicitly replaces legacy part numbers 025-38915-000 and S1-025-35394-000, ensuring zero-clearance mounting and proper wire harness fitment.
• Enhanced Combustion: Features a slow-opening mechanism that eliminates hard starts and delivers a quieter ignition sequence.
• Precision Pressure Control: Regulates gas flow at 3.5" WC and 1.6" WC to match factory specifications for consistent burner performance.

• Is this valve compatible with LP (Propane) systems? This valve is factory-configured for natural gas. For propane applications, a certified LP conversion kit must be installed.
• What is the benefit of a slow-open valve? The slow-open gas valve prevents the "boom" of hard ignition by gradually increasing gas flow, which reduces stress on the heat exchanger.
• Can I use this as a replacement for a single-stage valve? No, this is a 2-stage gas valve and must be used with compatible control boards and thermostats designed for staging.
