---------------------------------------------------------------------- Date: Wed, 12 Aug 2009 09:39:39 -0700 From: "Mike Sharp" <rdcpro at hotmail.com> Subject: Re: cleanable valves Matt asks for valve help... Some years ago I worked for a company that manufactures ultra high purity gas purification equipment. I used tri-clamp fittings everywhere for gas distribution (upstream of the purifier) and for all the UHP cleaning connections. You can machine a three piece ball valve with NPT ends so that it becomes a "sweat solder" fitting, and then silver solder a regular tri-clamp ferrule in. Depending on the tube size, the outer part of the threads might still be showing, but as long as you get a smooth surface on the inner end, you'll be fine. The solder wicks through, and fills the gap at the inner end of the ferrule, if you do it right. I also have several 1/2 and 3/4 inch tri-clamp valves I've bought from ebay, which is a heck of a lot easier than building. The easiest to clean are the butterfly valves, but ball valves work too. Frankly, I'm not so sure you'll have to actually disassemble the valve to clean it, if you recirculate cleaning and sanitizing solution while cycling the valve a bunch of times. I've also used a valve with compression fittings on 1 inch ferrules before, which worked well. I made tons of these. For bottling, these should probably be dismantled after use, since there is a small gap in the valve body where the ferrule meets. You can use a Delrin or Teflon compression ring, which is removable. I imagine you can find smaller ones that will work on the 1/2 or 3/4 inch tri-clamp ferrules. Regards, Mike Sharp Return to table of contents
