York S1-025-27720-700 Gas Valve

The York S1-025-27720-700 is an OEM standard-opening natural gas valve engineered for precision fuel regulation in residential and light commercial furnaces. This single-stage, 24V gas valve features a robust 3/4" NPT inlet and outlet connection, providing the high-capacity flow required for larger BTU heating applications. As a direct factory replacement, it is 100% identical to 36H32-466 (White-Rodgers), ensuring a drop-in installation without the need for manifold modifications. The solenoid coil is rated for 50/60Hz, maintaining stable operation even during peak demand. Technicians should note that while this unit is factory-calibrated for a 3.5" W.C. manifold pressure, the York furnace gas valve regulator is field-adjustable to meet specific manufacturer rise requirements. Its slow-opening characteristic prevents hard ignitions, extending the life of the heat exchanger and burner assembly. Designed for compatibility with hot surface ignition and direct spark systems, this 1/2 PSI rated valve is the primary solution for erratic flame signals or failed coil resistance in York and Johnson Controls units.

• Direct OEM Interchange: Serves as the exact factory substitute for the 36H32-466 and replaces older legacy part numbers S1-02527720000 and S1-02529046000.
• High-Flow Capacity: Equipped with 3/4" NPT gas valve ports to support high-efficiency furnaces and light commercial rooftop units.
• Precise Regulation: Integrated pressure regulator is factory-set for natural gas, maintaining consistent manifold pressure for clean combustion.
• Versatile Mounting: Multi-positional mounting capability allows for flexible installation in various cabinet configurations.
• Reliable Performance: Engineered with high-grade internal diaphragms to withstand wide ambient temperature swings from -40°F to 175°F.

Is this valve compatible with LP (Propane) conversions?
This valve is shipped for natural gas use. To utilize it with Liquid Propane, a specific LP conversion kit must be installed, and the regulator must be adjusted to the required 10" W.C.

Will this replace a 36H32-423 or other 36H series valves?
The S1-025-27720-700 is the direct spec for the 36H32-466. Always verify the voltage and port size (3/4" vs 1/2") before swapping, as pipe diameter and coil amperage vary between different 36H models.

How do I verify if the solenoid coil has failed?
Using a multimeter, check for 24V at the terminals during the ignition sequence. If voltage is present but the valve does not open, check the coil resistance; an open circuit or "OL" reading indicates a failed solenoid that requires valve replacement.
