Based on your examples, it sounds to me as though a "valve" is a vacuum
device whose major purpose is to control current flowing elsewhere in
its circuit, whereas a "tube" is anything else - a CRT's major purpose
is display, with the current flow incidental to that; Nixies,
dekatrons, and voltage stabilizers are cold-cathode gas-filled devices.
A trochotron...that's an interesting case. On the above (speculative)
basis I could argue for either "valve" or "tube".
Incidentally, thank you for mentioning trochotrons. I was not
previously aware of them, and now that I've read up on them a tiny bit
I'm glad I have.
