What controls the gas valve?
The furnace gas valve operates by electromagnets. The primary valve — also known as the safety valve — supplies gas to the pilot light. The second valve — also known as the main valve — allows gas to flow to the burner trays. The thermocouple (or thermopile) generates the power holds the safety valve open.
What safety device will shut down the gas valve?
While there are many safety devices required by codes and standards to ensure the safe operation of fuel-fired heating equipment, the safety shutoff valve (SSOV) serves as a key safety control device to prevent the flow of gas or oil into the combustion chamber when the equipment is shutdown or an abnormal condition
How do I know if my gas valve is on or off without a handle?
When the long side of the nub or handle is parallel to the incoming gas line, it’s open and the gas is flowing. When it’s turned a quarter turn, perpendicular to the incoming pipe, it’s closed.

How does a gas valve work without electricity?
Without millivolts of electricity being generated, the gas valve cannot open and will remain in the closed position. A pilot light has two primary functions. One is to generate millivolts in order to open and close the gas valve.
How does thermocouple controlled gas valve?
The thermocouple responds to changes in temperature by producing an electrical current that causes the gas valve that supplies the pilot light to open when the temperature is high or to close when there is no direct heat source.
Do gas meters have an automatic shut off?
Automatic gas shutoff valves are installed on the pipe between the gas meter and your house. Natural gas piping and appliances can be damaged during earthquakes and other events, causing gas leaks.
How much does it cost to install an earthquake gas shut-off valve?
Prices generally range between $250 and $750, including parts and labor. If you’re in an earthquake-prone area, a seismic shut-off valve is an important safety measure to prevent fires and explosions from your gas line during a seismic event.
Can a plumber shut off gas?

open and shut. Should have been obvious with the arrows. One can easily see the valve closure through the pipe because it is not installed yet.
How does a gas shut-off valve work?
Excess Flow valves are designed to cut off the flow of gas when they detect a higher flow rating than the allotted maximum flow of the home. If you have a line break, the escaping gas will cause excess flow detectable by the valve, which then immediately shuts off the flow of gas into your house.
How do I turn my gas back on myself?

Can you use gas stove when power is out?
In general, most gas appliances will still work, including the water heater, but gas stove burners are typically lit by electric ignition systems. You can use a match to light the burners and cook on the stove, but your gas oven still relies on electricity and likely will not work.
What is electronic ignition on gas stove?
The automatic pilotless ignition (also called automatic electric or automatic electronic ignition) eliminates the need to light the burners. It also saves money by using less gas than a standing pilot range. Because this system has no standing pilot light, no gas is being used unless it is needed.
Is it safe to light a gas stove with a lighter?
You can still manually light nearly every modern gas stove with a match or lighter, even if the igniter is broken. Matches are safer and will work better than typical cigarette lighters. Turn gas on medium.
