Williams 7131 Gas Valve

The Williams 7131 is a high-performance 4" WC Natural Gas Valve engineered for precise manifold pressure regulation in Williams wall furnaces and floor heaters. This 1/2" NPT gas valve serves as the direct OEM replacement for legacy part numbers P295300A and 7131GASVALVEKIT. Specifically calibrated for natural gas heating systems, it maintains a consistent 4.0-inch water column output to ensure stable combustion and optimal thermal efficiency. Built for rigorous field use, this 24V gas valve features standard NEMA terminals and a filtered inlet screen to prevent debris from compromising the internal solenoid or regulator assembly.

Professional contractors rely on the 7131 replacement valve kit for its "straight-thru" flow design and slow-opening feature, which facilitates soft ignition and reduces mechanical stress on the heat exchanger. This combination gas valve integrates a manual shut-off, pilot adjustment, and main regulator into a single compact housing, making it an essential component for maintaining HVAC system reliability. Whether you are servicing a Monterey top-vent furnace or a direct-vent wall unit, this valve provides the exact technical specifications required to meet factory performance standards without the need for field modifications.

• Universal Compatibility: Fully interchangeable with 7131GASVALVEKIT and P295300A for streamlined inventory management.
• Precise Pressure Calibration: Factory-set at 4" WC Natural Gas to eliminate the need for extensive onsite manometer adjustments.
• Soft Ignition Technology: Features a slow-opening actuator to prevent delayed ignition "booms" and extend component life.
• Robust Construction: Heavy-duty 1/2" gas valve body designed to withstand high-ambient temperatures in tight furnace vestals.
• Standard Electrical Interface: Operates on a standard 24V AC circuit with common spade terminals for fast wiring.

• Is the Williams 7131 compatible with Propane (LP)? This specific model is calibrated for Natural Gas at 4" WC. For LP applications, a conversion kit or an LP-specific valve (typically 10" WC) is required.
• Can this valve replace the Robertshaw 7000 series? Yes, the 7131 often replaces Robertshaw 7000DERHC equivalents used in Williams equipment, provided the voltage and pressure ratings match.
• Does this kit include the pilot thermocouple? This part number typically covers the valve assembly; always inspect the existing pilot line and thermocouple for wear during replacement.
