DIY pressurized CO2 component advice/?'s

I'll kick this off with does anyone know what the difference between an angle pattern toggle valve and a metering/needle valve is...I have found a Swagelok SS-1GS4 angle pattern toggle valve for cheap and they look almost identical to metering valves, is this just another term for metering or needle valve?

As the name implies, wouldn't a toggle valve just be on/off position, and not actually be able to control flow?

Ah, yes...and Therein lies the difference lol, the only difference in looks at least is the on off knob, on a metering valve it obv. Has a potentiating knob, on the toggle valve it has just a on off knob, I'm assuming I'm not lucky enough to be able to convert one into the other huh?

You'll notice that the construction of each valve is different.

Toggle valve:



Metering valve:



I'm not sure how you would propose converting from one to the other.
