Robertshaw 700-456 1" Slow Open Gas Valve 3.5" WC 120V

The Robertshaw 700-456 Gas Valve an essential component of an HVAC systems. Designed to control flow of gas to burners in furnaces, boilers, and water heaters. It has a slow opening mechanism that lets out gas gradually, minimizing pressure build-up and making the ignition process simpler on the system. The valve is opened by the signal from the thermostat or control board when it is connected to the 120V power source to allow the gas to flow through at a regulated rate. This control operation also increases safety, avoids ignition delay, and decreases damage. It has an inlet of 1” and a working pressure of 3.5” WC, which helps in achieving efficient combustion and maintaining the heat output.
