CO2 Needle Valve Questions - Equipment

timewalker03 · 12-04-2008, 03:53 PM

I need some advice for a CO2 Needle valve to help regulate the flow of CO2 once I go Pressurized. I have looked at the one sold on DrsFostersmith and found the price to be steep. about 37.00 before shipping. I was wondering if anyone had any ideas either for a DIY or some pre made needle valve that is less than what was listed above. Basically I am looking to find one that will allow control down to 1-2 bubbles a second. I already have my regulator and solenoid, but now need the needle valve. I have tried a basic plumbing needle valve, but even the smallest is threaded to large to keep the flow at 1-2 bubble/sec. Any help would be great. Thanks!

There are a few good needle valves available. A Lot of people use the clippard or the fabco valves. I have a couple of both and prefer the fabcos myself but the clippards get the job done and are cheaper. Here's a link to a site that sells both,

I had the same problem trying hardware store needle valves, so I just broke down and bought a co2 one.

P.S. I have both the Victor single stage regulator and the ideal needle valve and could not be more pleased with there performance.

Link doesn't seem to be working. But as an aside, I have no experience with CO2 regulators yet (previous tank was el natural) but having used Victor regulators for my oxy-acetylene welding torch for several decades I can vouch for their quality and will probably go that way when I get a CO2 regulator myself.

Everyone thanks for the help. Someone had an extra one so I purchased for what I could afford. Thanks again all for the help. This site is unbelievable for the amount of help a person receives in a short time.

I'm glad that you found one.

I got this $134 Swagelok SS-31RF2 metering valve for $0.99 plus shipping on eBay.
