I'm using Clippard valves on all my tanks now and have found them to
be satisfactory. Models MNV-4K or MNV-3K should work for you. Their
flow to turn ratio are almost identical at the bottom end that you
will be working at.


I tried the MNV-4K. While it works, it doesn't give fine control. Mine goes
from 1 bubble per second to something like 30 bubbles per second over
a tiny fraction (maybe 2 degrees) of a turn. The Swagelok valve is much
better than that.

Cheers,

Michi.

Michi what was the pressure on the valve?
I'm using 8 psi and its working well for me.
The Swagelok valves are a better quality but they have a price tag
that goes along with that.

take care
