There is plenty of time right now, to put together some more nice exhibition grade custom co2 systems.

I ran out of parts lol. Did you customize the 10-32 nut to fit the 1/8 tube needle valve?

yes, the stainless steel 1/8 tube end to 1/8 npt adapters are plenty on evil bay, but they are weak at the tube, imo, so I make my own adapters.

Now you guys are just showing off! I really enjoy seeing the configurations to both keep consistent material types (stainless steel) and to keep the components as compact as possible.

nice!
if you don't see the sticker that shows you the needle cartridge model(the number in the below picture), you can check the the second line on the tag, is max flow rate rating, let me know max flow rate number, so I can decide it is cartridge model.
if the number is less than 3B, as in picture, are good, best if it is SS1.

big white sticker looks to list the max flow (XX)0 sccm(inute)
1L/min = 1000cc/minute


Charts in L/min at various pressures..
1mPa = 9.9atm say 10.
.1mPa = 1atm

soo if sticker says 110 Sccm then should be a #S1 IF I 'm looking at this right.

Err.. ONE thing to mention.. Not seeing this in US threads
SPEC sheet isn't really clear to me though..
Rc 1/4 or Rc 1/8
British standard..
These will mate w/ US BUT will leak...
Looks like you do have some fittings though.. looks "tubish" but prob metric?
Not cheap valves.. best est. is about $250 US give or take a bunch..

It takes about 3-4 full turns to see a bubble coming out. This valve is surprisingly fine.

there are some other valves are in this flow control precision, about 50 to 100 sccm as max flow rate, but most are not looking good as the one Alan has though.

Put this together yesterday, I think it is the best parts I can find for a brass co2 system.

I finally located a 0.52 watt Parker Hannifin series 9 solenoid, it is the brass version though, so have to build this brass version co2 system with a brass Brooks instrument NRS metering valve(another rare find, a series one NRS metering valve with digital counter handle).

this style can be copied with the ideal series 2 angle pattern needle valve and manifold mounted clippard solenoid(which are both available on the evil bay). The key to make the brass system look good is to polish the brass until mirror shine.
