It's a service valve brazed to brass niple. Doesn't it look so good? ;)
good luck with that regulator, it looks as if its meant to regualte flow which could be a problem for charging.

Why could it be a problem, can you explain?
you wont get a high pressure out of it, therefore you cant static charge and may possible have some problems charging in general.

I think that regulator is made for supplying co2 for beer/food etc. I couldnt find a regulator that output high eneough pressure so I bought a nitrogen regulator and a CGA 580 (n2) to CGA 320 (CO2) adapter. Now I can get 0 -350+ psi out of the co2 bottle.

Oh.. that so
I have two CO2 regulators and they've used for MIG welding tools
Maybe this second regulator is enough for charging vapor change units?
(I couldn't understand how to read pressure in bar, or psi)

look for a regulator for C02 filling stations for paintball equipment. Check out www.888paintball.com and www.paintballgear.com, they should have something. LMK if you need help.

Actually the second regulator will work fine change the hose fitting to 1/4 flare for your hoses. The first will work also but you will have to charge only runing systems and it would be easy to over charge.

Thanks
chilly1, should you instruct me to read max out pressure? I still don't know how to
read it in bar or psi.. I know only that 1MPa is equal to 10 bar or 145 psi and dm^3/
min is a flow unit, not pressure unit.
And say, what is this "teh"?

"teh" is "the" which is often misspelled typing fast. Chilly do you have any thoughts about the ratio of CO2:R290 in an autocascade? They both have the same molecular mass so for say a 1:2 ratio I could charge 15psi CO2 and 30PSI r290?

Ok, I understand
gkiing, I don't think it's easy to know about this ratio.. well, autocascades are something
new and they're not tested (differrent HXs, constructions, pressures etc.) fairly yet
But who know what chilly1 know ;)

Well the ratio is dependant upon the HX size and metering devices to achieve balance.

In other words, gkiing, you must get this ratio with trials and errors method
easiest way is to get the hx cold with r290 then add some co2 playing and time you will no if it needs more r290 or c02.
basically if you got too much co2 in there high pressure will rise high.
then letting gas out can add exta r290 and start again.
you need enough r290 in system running keep hx cold and not too much c02 to the point that high pressure is too high.
