Auf = open zu = closed
probably because some of the gas trapped inside coke is realeased when you open it.
It regulates the amount of gas- or flow of the gas. As you open the valve the gas pours out faster. Even though it is at the same pressure as you are putting into the burner much less is coming out.
Yes, locate the gas meter for the residence in question and look for the valve which permits the gas to enter the meter. If the gas has been shut off by the gas utility, there will be a lock (usually a padlock) locking the valve in the closed position. The resident will usually have received a number of notices for non payment, and finally a notice of eminent shut off.
Usually gas appliances come with an extra valve in with the instructions. Just replace the valve. You may have to ask a heating specialist how to find the connection on your gas line. But it is not too difficult.
the gas leaks out
A butterfly valve is from a family of valves called quarter turn valves. The "butterfly" is a metal disc mounted on a rod. When the valve is closed, the disc is turned so that it completely blocks off the passageway. When the valve is open, the disc is rotated a quarter turn so that it allows unrestricted passage. The position of the disc is effected from outside the valve. gas butterfly valve is one kind of butterfly valve, the main feature is that all the functions are supported by gas just as the Electric Butterfly Valve which supported by electric.

The gas valve is an electrically powered device that is wired at the end of a series circuit so that it can only be energized (open) if all of the safety switches upstream in the circuit are closed and the pilot flame is lit on a standing pilot furnace.
If you measure "the applied voltage" (typically, 24 volts) across the coil of the main gas valve, and the valve refuses to open, it will need to be replaced. Before you do, double-check that gas is getting to the valve.The HVAC Veteran
P0400 - Exhaust Gas Recirculation Flow Malfunction Possible causes - Exhaust Gas Recirculation (EGR) solenoid valve harness is open or shorted - Exhaust Gas Recirculation (EGR) solenoid valve circuit poor electrical connection - Exhaust Gas Recirculation (EGR) volume control valve stuck closed - Faulty Exhaust Gas Recirculation (EGR) volume control solenoid valve - Dead (Weak) battery - Faulty EGR temperature sensor and circuit - Faulty EGR Valve
If your main gas valve is stuck in the closed position, it must be replaced. This condition is the reason your thermostat will not cause the main burners to light.
No. The pilot valve is closed when no flame is sensed by the thermocouple.
The purge control valve may be the culprit. It is solenoid valve which allows gas vapors into the engine to be burned off while you're driving, normally the valve is closed. For the vehicle to stall only after filling up, this valve would need to be stuck open. It may be operating normally when you test it if this is not happening every time you fill up, though your best bet would be to replace it.
Starting at the beginning, Leaky petcock, carb floats stuck open or incorrectly set, fuel running into the intake past the open intake valve or past a closed intake valve with a bad seat, then leaking past the rings on the piston into the crankcase.
All stores are closed
The valve may be blocked or the gas cylinder/ supply is empty.
