The gas valve controls the pilot light and the water temperature.
When lighting the pilot of gas stove valve, the button on the valve is pressed and a small amount of gas is sent to the pilot head. After the pilot is lit it will heat the thermocouple.
The thermocouple will send a small electrical current to the control valve. When the gas valve receives the current, an electromagnet will open a safety valve and allow gas to continue to flow to the pilot. At this point the pilot button can be released. The pilot will continue to burn.

There are two probes protruding out of the back of the valve.
The shorter probe is a safety device. If the thermostat malfunctions and water continues to heat the probe will interrupt the gas flow. It is called a high limit probe.

The longer probe is the temperature probe. As the water heats and
cools a rod inside the probe pushes a lever in the gas stove safety valve and cuts
the gas on and off according the the temperature setting.
