The valve doesn't regulate pressure, but rather FLOW RATE.  We usually
measure this by bubble count.  That's what's really important at the last
stage anyway.

btw, I disagree about the "cheesy valve" approach.  The problem is not
just the ability to adjust it, but the valve's stability over time.
The cheaper ones will drift open or closed.  In my experience, I
definitely notice the difference between the Nupro $50 valve (very
stable) and the $12 ARO valve (not so stable, but still usable).
