How does thermocouple work on gas valve

WebA thermocouple, also known as a "thermoelectrical thermometer", is an electrical device consisting of two dissimilar electrical conductors forming an electrical junction.A thermocouple produces a temperature-dependent … WebA Thermocouple generates voltage when its heated, and the voltage varies with the heat. A Thermopile is a collection of thermocouples (in a single package) that generates more voltage. So, the voltage to open the valves comes from thermocouples and the heat comes from a pilot light.
