Science labs are equipped with gas cut off valves in case of an emergency where all gas needs to be turned off at one; such as a gas fire. In such cases it can save lives and minimise damages.

A Bunsen burner is commonly used in labs to heat things up. It is a metal device that connects to a gas source and produces a flame for heating purposes.
A thermocouple on a gas heater operates by generating a small voltage when heated by the pilot flame. This voltage signals the gas valve to stay open, allowing gas to flow to the burner. If the pilot flame is extinguished, the lack of voltage from the thermocouple will cause the gas valve to shut off, preventing a gas leak.
The desk outlet valve of a Bunsen burner controls the airflow of the gas entering the burner. By adjusting this valve, you can regulate the amount of oxygen mixing with the gas, which in turn affects the type of flame produced and the temperature it can reach.
The gas flow in a Bunsen burner is typically controlled using a valve located on the gas line connected to the burner. By turning the valve, you can increase or decrease the flow of gas entering the burner, which in turn affects the size and intensity of the flame.
The pilot may not be lighting due to a problem with the gas supply, a faulty thermocouple, a clogged pilot tube, or a malfunctioning control valve. Check for gas supply, ensure the pilot area is clear of debris, and consider replacing the thermocouple if necessary.

No, but I would stop wasting gas if I were you.
To get all of kinds science equipment/apparatus go to Wikipedia.com and look up pH meter, high performance liquid chromatography (HPLC), gas chromatography mass spectroscopy (GC/MS), pipettes, vortex, electrophoresis, and a desiccator. This should get you started.
Replace the valve unless it is rebuildable. If you pull it out it may have an O ring you can replace.
Is the gas valve turned on?
The gas valve is closed.
A redundant gas valve is a safety feature in a gas system where two valves are installed in series to ensure that gas flow can be shut off if one valve fails. This redundancy helps prevent gas leaks and potential hazards.
The gas valve is currently in the off position.
A gas-collecting tube is made of glass and has a cylinder shape with a valve at one end of the cylinder. Most gas-collecting containers have a gauged volume on them. They are used in science for the purpose of taking samples of a gas.
There are pressure regulator valves that exist. The purpose of these pressure regulator valves is to cut off the flow of a liquid or gas when the pressure within the valve reaches a certain level.
Typically, it is going to be the gas valve. The system sends a 24 volt signal to the gas valve and it opens. I you are getting 24 vols to the gas valve and no gas, it will be the valve.
The gas line valve is currently off.
