Swagelok regulator! it is really nice, they are the same as "GO" regulator.
I have a new swagelok reg too, will build it.

a queston though, why ideal needle valve? there are so many look better and function better, they are the high precision metering valves at least double a stainless steel ideal in retail.

what kind of solenoid you are going to use? Brass or SS?

For stainless steel, 1/8 npt port type solenoids, besides the burkert 2822, burkert type 200, recently acquired a new brand XXXXXX(not yet reveal the name)

I found a nice, low price bid, Praxair Heavy-Duty Gas Regulator, Model 2123381-580 on ebay. I think this Concoa reg re-branded Praxair reg.

e b ay item no: 221198595007
ending in 1 day.

Yeah most Praxairs I've seen are rebranded Concoa's. It looks pretty nice, though the 200 psi gauge is at the high end of ideal. 120 psi would be the max of a 200 psi 212, which is more than twice what we'd ever need. Still I use a 212 as one of my personal regs.

It's worth the price if nobody else bids much.

I like them. I built a few regs with the V54-1-12 but have never personally owned one. I also really like the way they look and that was one of the biggest factors involved with using it. (probably... the cost is bothering me) Honestly, some of these really low flow models are a bit over the top as far as our needs go.

I have a couple different stainless Burkerts sitting around. A 200 series and a 6011. Not sure yet. I want to use something that I don't need to use a wall wort with.

Few years ago I won 212 series on e bay for just $9.99. Shipping was about $17. Concoa regulators are just huge.

the seller has 4 of the same model,
after this end will be another.

take turn to grab so competition don't push up the price.
don't count me in, no more Concoa 212 for me and I need to work on the chiyoda seiki and the stainless steel Victor SGT500

I'm done with concoa. They're just too big for me.

Not all concoas are huge. The 300 series is pretty compact. It's really just the 200 and 400 series that are hefty.
