York 325-47851-000 Gas Valve Kit

The York S1-325-47851-000 Gas Valve Kit is a heavy-duty 3/4" 24V Natural Gas Valve engineered for precise fuel regulation in high-capacity residential and commercial furnaces. This OEM component serves as the direct replacement for York 025-47851-000, ensuring full compatibility with existing burner assemblies without requiring manifold reconfiguration. Built to manage natural gas flow with high-grade metal alloys, this valve maintains consistent combustion pressure even under the rigorous cycling demands of high-efficiency HVAC equipment. For technicians troubleshooting ignition failure or erratic flame rollout, this kit provides a definitive solution to furnace gas valve replacement, restoring factory-spec performance to the heating system. The 24VAC electrical interface integrates seamlessly with standard York control boards, providing reliable solenoid operation and safety shut-off capabilities.

• OEM Compatibility: Serves as the engineered York S1-325-47851-000 replacement for the obsolete 025-47851-000 and S1-025-35303-000 models.
• Standardized Ports: Features a 3/4-inch NPT connection for universal integration with standard natural gas plumbing lines.
• Electrical Reliability: Designed for 24V furnace gas valve circuits, ensuring low-voltage control signal accuracy.
• Durable Construction: High-grade housing resists thermal stress and vibration to prevent leaks and mechanical sticking.

What are the signs that my York gas valve is failing?
Common indicators include the hot surface igniter glowing without flame production, intermittent "no heat" calls with a 15Hz signal present at the valve, or the unit locking out due to a "gas valve circuit error" on the control board.

Is this valve compatible with LP (Propane) systems?
This specific kit is configured for natural gas applications. To use this in an LP environment, a certified propane conversion kit must be installed by a licensed technician to ensure proper orifice and spring regulation.

Does this kit include a wiring harness?
Yes, as a complete kit, it typically includes the necessary harness components to ensure a secure electrical connection to the system's control module, addressing common pin-connection failures found in older units.
