OUsnakebyte February 17, 2011 Share February 17, 2011 Looking for finer-tuned control of my calcium reactor input - more than the ball valve gives. I don't think 1/4" RO tubing gate valves exist, but I figured I'd ask. Cheers Mike Link to comment Share on other sites More sharing options...
Dragon Eye February 17, 2011 Share February 17, 2011 Yes, there is one and I've seen them online. But, I can't find them now either and I'm looking for one too. So, if you find them, please post. Link to comment Share on other sites More sharing options...
Chad February 17, 2011 Share February 17, 2011 I haven't seen gate valves that small, but a needle valve should do the trick for you as they are able to be pretty finely tuned, although I would expect them to foul over time since the internal parts are pretty fine. Here is a link to what I mean, this one has JACO fittings as an option http://www.specialtymfg.com/needle_valves/586_needle_valve/default.asp and this one looks awesome, but probably more than you are thinking http://www.google.com/imgres?imgurl=http://img.directindustry.com/images_di/photo-g/plastic-needle-valves-431338.jpg&imgrefurl=http://www.directindustry.com/prod/aalborg-instruments/plastic-needle-valve-9050-431338.html&usg=__HQmJv87Ci-4bHhcpxPk7XVl0RTM=&h=365&w=267&sz=19&hl=en&start=6&zoom=1&um=1&itbs=1&tbnid=0FH5qWE6XOcVJM:&tbnh=121&tbnw=89&prev=/images%3Fq%3Dplastic%2Bneedle%2Bvalve%26um%3D1%26hl%3Den%26tbs%3Disch:1&ei=4h5dTemhBYK0lQfrw5jWCg Link to comment Share on other sites More sharing options...
Dragon Eye February 17, 2011 Share February 17, 2011 That's it! No wonder I couldn't find it again, I was searching for the wrong type of valve. http://www.usplastic.com/catalog/item.aspx?itemid=32220&catid=662 Link to comment Share on other sites More sharing options...
Chad February 17, 2011 Share February 17, 2011 They are basically the same thing. The one you found is WAY cheaper than the ones I found! Link to comment Share on other sites More sharing options...
OUsnakebyte February 17, 2011 Author Share February 17, 2011 You all ROCK!!! Awesome, thanks. The second one you posted, Chad, looks like the Rolls Royce of small valves... Thanks again all. Cheers Mike Link to comment Share on other sites More sharing options...
Chad February 17, 2011 Share February 17, 2011 haha, I was thinking along similar lines when I saw it, I had to share! Glad to help! Link to comment Share on other sites More sharing options...
mogurnda February 17, 2011 Share February 17, 2011 For my reactor, I used one of these (http://www.usplastic.com/catalog/item.aspx?itemid=32209&catid=662) with 1/4" JG adaptors. Nevermind, just saw the same thing linked a few posts up. Link to comment Share on other sites More sharing options...
