sell it to me
I will add another metering valve, to make them inline for fine bubble adjust.
so two metering valves together look GOOD.

Put more metering/needle valves inline, the adjustment is much precise, I am going to give it a try.
I plan to use the SMC AS1000 valves I have, to make them two each group(inline, their inlet/outlet are really easy to connect), so finer adjustment.
