Williams P295200A Gas Valve

The Williams P295200A Gas Valve is a critical natural gas control valve for technicians servicing Williams Direct Vent Wall Furnaces. Engineered for precision gas regulation, this 1/2" NPT gas valve is factory-set to a 4" WC (Water Column) manifold pressure, ensuring optimal combustion efficiency and thermal output. It serves as the primary gateway within the control assembly, managing fuel flow for 14,000, 20,000, and 30,000 BTU models, specifically the 1403822, 2003822, and 3003622 series. This millivolt-compatible component is designed to withstand the rigorous duty cycles of residential and light commercial heating applications. When diagnosing pilot outages or erratic main burner ignition in direct vent furnaces, this valve provides the reliable pressure regulation required to maintain safe operating parameters and prevent nuisance shutdowns. Its direct-fit configuration simplifies the swap-out process for field contractors, maintaining the integrity of the original equipment manufacturer (OEM) specifications.

• System Specific Compatibility: Engineered specifically for Williams 1403822, 2003822, and 3003622 furnace models, ensuring correct BTU input and orifice alignment.
• Precise Pressure Regulation: Fixed at 4" WC for Natural Gas, eliminating the need for complex field adjustments during installation.
• Enhanced Pilot Stability: Robust internal diaphragms provide consistent flow to the pilot assembly, reducing service calls related to thermocouple dropout.
• Industrial Build Quality: Constructed with heavy-duty alloys to resist corrosion and mechanical wear in high-temperature environments.

Is the Williams P295200A compatible with LP Conversion kits?
This specific part is calibrated for Natural Gas at 4" WC. For Propane (LP) applications, a specific conversion kit or a dedicated LP valve must be used to ensure safe manifold pressure.

What are the inlet and outlet sizes for this valve?
This valve features standard 1/2 inch gas line connections, allowing for standard hard-pipe or flex-connector integration in most wall furnace cabinets.

Will this work with a 24V transformer system?
The P295200A is typically utilized in millivolt control systems common in Williams wall furnaces, relying on a thermopile/thermocouple rather than an external 24V power source.
