Williams P501705 Gas Valve

The Williams P501705 Gas Valve is an essential OEM component tailored specifically for natural gas heating systems. Engineered with a 1/2" NPT inlet and 1/2" NPT outlet, this snap-action gas valve maintains a precise manifold pressure of 10.5" WC (water column). Built for reliability in high-demand environments, it is rated for approximately 70,000 BTU on natural gas applications. This combination valve functions as both a low-voltage control and an adjustable pressure regulator, ensuring consistent fuel delivery to the combustion chamber. As a seasoned technician knows, maintaining the correct Williams wall furnace gas pressure is critical for equipment longevity and safety. The P501705 provides a robust solution for repairing or maintaining Williams wall furnaces and console models, facilitating direct HVAC replacement parts integration without the need for extensive field modifications.

• Precise Pressure Regulation: Factory-set at 10.5" WC to ensure stable natural gas flow and optimal burner performance.
• OEM Compatibility: Designed specifically for Williams furnace models, including those requiring the 7136 valve kit.
• Compact Configuration: Features standard 1/2" connections for straightforward piping and mechanical fitment.
• Manual Shut-Off: Includes an integrated manual valve for safe servicing and system isolation during maintenance.

• Can this valve be used for LP (Propane) conversions? While some combination valves support dual fuel with a conversion kit, this specific model is factory-configured for Natural Gas at 10.5" WC. Always verify your specific model's manifold pressure requirements.
• Does this replace older Robertshaw or Honeywell valves? Yes, the P501705 is the designated replacement for several legacy parts, including R2701 and R2703 units found in Williams wall furnaces.
• What voltage is required for the solenoid? This unit operates on a standard 24 VAC control circuit typically found in residential and commercial heating systems.
