Look like it's used for flow control, like any tap really.

Why does it matter? Doesn't look very useful to the average spudder at all.

The springy thing is just a flow control as JSR said, just pull it up to let it flow, and the spring returns it.

Looks like a gas cock as could be found on a lab bench. Just a ball valve.

Unless someone wanted to really overcomplicate a ball valve by adding flow control on top of the fact you can partially open a ball valve anyway I'd expect the bolt and spring to just be retaining parts for the handle.

I consider it to not be dissimilar to this in the category Gas Cocks.

Other gas cocks also have the retaining spring and screw at the bottom.

those can be used as drain valves for air compressor tanks, bleeder/drain valves for radiators.

It's just a simple valve, like a ball valve. Instead of a ball inside, it is a cylinder. There are no rubber or plastic seals inside. The spring at the bottom is to keep things together at a tension that still seals well but doesn't jam everything too tight. They are usually used for lower pressures, I'd say 100 psi or less because they have a tendency to leak. The specific valve in question is made to bleed off and/or drain fluids and liquids.
