OK I've read the equipment primer on needle valves and found out a few thing interesting
1)Common known precision ones are expensive (relatively speaking)
2)Needle valves in general are not so expensive.
In my search for a middle ground I came to a conclusion that Swagelok may be the easiest and cheapest to find..
I also came upon a question I'd like answered..
This chart shows the needle performance of the coarser swaglocks B2(4,6) series (w one teeny exception)
any w/ a "R" would have the regulating needle..
anyone care to translate this chart into practical speek.. i.e some approx. of bubbles per secong
