York S1-7956-336P Gas Valve

The York S1-7956-336P Gas Valve is an essential component for maintaining combustion stability in residential and light commercial heating systems. As a direct OEM replacement for 7631A3261, this valve is engineered to restore factory-spec performance in Coleman and York furnaces. This 24V intermittent pilot valve features a compact design with standard 1/2" NPT inlet and outlet ports, ensuring a clean fit within narrow furnace cabinets. It is rated for LP/NAT gas control, offering the versatility required for field conversions when paired with the appropriate orifices. The redundant solenoid architecture provides precise fuel regulation, which is critical for achieving optimal manifold pressure and burner efficiency. For technicians performing high-demand service calls, this HVAC gas control valve offers reliable terminal connections and a rugged housing built to withstand the thermal cycling typical of high-efficiency equipment. Replacing an aged or sticking valve with this genuine service part ensures proper ignition sequences and system safety.

• Universal Compatibility: Serves as the factory-authorized 7631A3261 replacement for simplified inventory management.
• Dual Fuel Utility: Correctly handles both Natural Gas and Liquid Propane applications with proper conversion.
• Standardized Fitment: Features 1/2" x 1/2" NPT connections for easy integration with existing manifold piping.
• Technician-Friendly Design: Utilizes standard 24V wiring and clear port labeling for faster installation and testing.

Is this gas valve compatible with both LP and Natural Gas?
Yes, the valve is designed for use with both fuel types; however, ensure the correct conversion kit and orifices are installed to match the fuel source at the site.

Will this replace my older York or Coleman 7631A3261 valve?
Yes, this is the current technical replacement part for that obsolete number, maintaining matching electrical and physical specifications.

Does this valve require a specific ignition module?
This valve operates on a standard 24V signal and is compatible with most intermittent pilot and direct spark ignition systems used in York-family furnaces.
