White-Rodgers 37C73U-172 Valve

The White-Rodgers 37C73U-172 is a robust universal gas water heater valve engineered for precision temperature control in natural gas water heaters. This replacement gas control valve features a thermal range of 70°F to 160°F, ensuring stable hot water delivery for residential and light commercial applications. Designed as a versatile solution for technicians, it includes a single-stage gas valve configuration with a 2.25-inch shank length and a 1/2" NPT inlet/outlet for standard HVACR piping configurations. The integrated energy cut-off (ECO) system provides a critical safety layer by interrupting gas flow if water temperatures exceed safe limits. This White-Rodgers gas valve is prioritized for its field reliability, offering a direct OEM replacement path for numerous legacy units. By utilizing a high-output thermopile or thermocouple system, it maintains consistent pilot burner operation, reducing nuisance outages and simplifying the water heater valve installation process for contractors in the field.
