Most folks probably don't need a needle valve that shuts off. But I
run multiple tanks off of a single regulator. Sometimes I may break
a tank down for extended periods (lately to store it until I have
more free time), and it is far easier for me to just shut the gas off
at the needle valve than rebuild the manifold, plug the port, or add
a second valve to close off the line. If the CO2 rig was only
driving a single aquarium, I wouldn't care if the needle valve shut
off or not. I'd just close the bottle valve.
