Replacement Gas Valve

This universal single-stage, fast-opening combination gas valve is engineered for standing pilot ignition systems in residential and commercial heating applications. Designed as a direct replacement for White-Rodgers 36C03-433 units, this valve features 3/4in x 3/4in female NPT connections and includes a reducer bushing kit (3/4in to 1/2in and 1/2in to 3/8in) for flexible installation configurations. The valve operates on 24 VAC at 60 Hz with a current draw of 0.23 A, making it compatible with standard HVAC control systems. With a nominal capacity of 280,000 BTU/hr for natural gas at 1in pressure drop, or 453,600 BTU/hr for LP gas, this valve delivers reliable performance across various heating system sizes. The integral regulator maintains consistent outlet pressure with settings at 3.5in W.C., with operating ranges of 2.5-5.0in W.C. for natural gas and 7.5-12.0in W.C. for LP gas. The fast-opening design enables rapid response to pilot flame detection, enhancing system reliability and safety. This combination valve consolidates pilot solenoid, main gas valve, and pressure regulator functions into one compact unit, reducing installation complexity and maintenance requirements. Suitable for furnaces, boilers, and other gas-fired heating equipment requiring standing pilot operation, this replacement part delivers OEM-equivalent performance at competitive pricing.
