I have this:
VDW21-5G-1-01-N-G-F

Which is pretty much the same as yours but with a different config. You can always call up SMC and ask them directly, but I think you will be fine. I'm no scientist but I think pure water is actually a mix of two gas. Jury is still out on that one.

I would of prefer that awesome wire out of the solenoid, that looks nice and clean.

Pretty sure that's the 20 series meaning that specific configuration is 2.3mm orifice and 1/8 NPT connections.

Oh yes it's 2.3mm orifice. Is it too big?

I found this SMC solenoid chart. It tells exactly what you have based on the model #.

Alan, sorry didn't have time to check TPT,
it is 1/8 BST, not NPT

Please look into the detail on PDF.

There are about three version of the SMC VDW solenoid PDF, the one Alan provide, I believe is the most detail and recent.

Care to share? I just got a Matheson 8L-590 off the bay, and am looking to start piecing it together. I was looking at the Clippard Solenoid, but can't figure out which Needle valve to go with. My budget is less that 40$ for the needle valve.

As Bettatail mentioned, the NV-55-18 is convenient because it is commercially sold and readily available from suppliers.

There are better metering valves that can be had for a similar price or less. These afford better (finer) control over the CO2 flow rate compared to the NV-55-18. Such metering valves take a little more effort to find, however.

I believe the Clippard solenoid has a 1/8" NPT fitting on each side (check the PDF specification sheet to be certain).

Thanks, I didn't know it wasn't NPT. I looked it up on the pdf but might have skipped this part.

Needle valve is the most painful part in the build, not so much info is given out. I hear a lot of people say "there are better needle valves..." but they never specify the models.
