Anyone have recommendations for a U.S. supplier of small (tiny?) valves =
for use with chemical solutions?  The flow rate should be somewhere in =
the neighborhood of 30L/Hr (1/2L per min.) and operate at less than 5 =
PSI.  Ideally, I'd like to run from 5VDC, but can use other (low) =
voltages if need be.   Response times for open/close aren't critical, =
and I wouldn't necessarily say they "must" be solenoid types if =
something else is equally suitable.
I've been looking all over the web and see a *lot* of possibilities out =
there, but wonder if any of you folks have actual experience with these =
things.
Thanks for any ideas!
Jim
