York S1-025-41091-000 Gas Valve

The York S1-025-41091-000 Gas Valve is a critical intermittent pilot combination control designed for high-performance residential and light commercial heating applications. Engineered for precision, this Honeywell VR8204Q2954 gas valve utilizes a 24V control circuit to regulate fuel flow to the burners, ensuring optimal combustion and thermal efficiency. As a dual automatic valve, it features a redundant solenoid for enhanced system safety and a manual shutoff for streamlined field maintenance. The low-pressure gas valve architecture manages gas flow with precise servo regulation, maintaining stable outlet pressure even during supply fluctuations. This HVAC gas valve replacement is a direct match for many York furnaces and rooftop units, specifically engineered to provide exact timing and flow rates required for intermittent pilot ignition systems. Its compact 1/2-inch NPT inlet and outlet ports allow for simplified integration in tight furnace vestibules, making it a reliable choice for field technicians seeking to restore equipment to original factory performance standards.

• Precise Fuel Regulation: Integrated servo pressure regulator maintains consistent gas delivery to burners, maximizing efficiency and heat output.
• Redundant Safety Seals: Features a dual-valve design with a redundant solenoid to ensure positive shutoff of gas flow when the thermostat is satisfied.
• Intermittent Pilot Compatibility: Specifically calibrated for use with standard IP modules to provide reliable ignition across varying environmental conditions.
• Durable Construction: Built with high-grade components to resist the rigors of high-cycle operation in demanding HVAC environments.
• Standardized Threading: Features 1/2" x 1/2" NPT connections for a direct fit, reducing the need for field modifications or additional adapters.

What are the symptoms of a failing VR8204Q2954 gas valve?
Technicians typically observe a failure to open the main burner after successful pilot ignition, or erratic outlet pressure causing noisy combustion. Testing the valve coil for resistance (typically between 11 and 15 ohms) or checking that the 24V signal is reaching the solenoids are standard diagnostic steps.

Can this valve be converted for Liquid Propane (LP) use?
While this model is typically set for Natural Gas, it is compatible with specific conversion kits (such as Honeywell part no. 393691). Ensure the regulator is field-adjusted to the manufacturer-specified manifold pressure after any orifice change.

Is this a direct replacement for discontinued York gas valves?
Yes, the York S1-025-41091-000 is the current manufacturer-designated replacement for several legacy part numbers. It maintains the same physical dimensions and electrical requirements as previous iterations.
