York S1-8955-3251 Gas Valve

The York S1-8955-3251 Gas Valve is a critical OEM replacement component designed for high-performance furnace and heating assemblies. Engineered specifically for liquid propane (LP) applications, this 24V gas valve maintains a precise manifold pressure of 11" WC, ensuring optimal combustion efficiency and burner stability. With a standard 1/2" NPT inlet/outlet, it facilitates a direct-fit installation into existing fuel lines, reducing downtime during field service calls. This low-pressure gas valve is built to withstand the rigorous duty cycles of residential and light commercial HVAC systems, providing reliable solenoid operation and consistent fuel regulation. For technicians troubleshooting intermittent ignition or pressure drops, the S1-8955-3251 offers the specific millivolt/voltage response required by York control boards to maintain safe operating parameters. Utilizing this genuine York furnace part preserves the original equipment's engineering specifications and combustion profile.

• Precise Fuel Regulation: Factory-set for 11" WC LP systems to ensure correct BTUH output and prevent soot accumulation.
• Standardized Connectivity: Features a 1/2" gas valve connection for seamless integration with commercial and residential black iron or CSST piping.
• OEM Compatibility: Designed as a direct replacement for York S1-8955-3251, ensuring electrical and physical alignment with the furnace chassis.
• Reliable 24V Control: Heavy-duty internal solenoids respond instantly to thermostat and limit string signals for safe startup and shutdown sequences.

Is this valve compatible with natural gas?
No, this specific model is configured for 11" WC Liquid Propane (LP) only. Using this on natural gas systems without a conversion kit (if applicable) will cause improper combustion.

Does this valve include the LP conversion kit?
This is a dedicated LP valve. Always verify the orifice size and manifold pressure requirements of your specific furnace model before installation.

Can I use this 24V valve in a millivolt system?
No, this component requires a 24VAC signal from the transformer or integrated furnace control (IFC) to actuate the gas flow.
