sailorman9 Posted January 26, 2017 Share Posted January 26, 2017 I'm setting up a storage tank for 185 proof Rum. Seeking a valve that won't impart a plastic taste due to the plastic seat. I have tried Nylon and EPDM so far, Yuck! I bought a used valve that is all Stainless Steel, but it has a bit of pitting and thus it drips. Would like to find another like this, but I can't find anything like that. Anyone have ideas? Link to comment Share on other sites More sharing options...
Silk City Distillers Posted January 26, 2017 Share Posted January 26, 2017 What's the fitting? For high proof I prefer teflon/ptfe seals on a stainless valve body. Nylon wouldn't be my first choice. 1 Link to comment Share on other sites More sharing options...
sailorman9 Posted January 26, 2017 Author Share Posted January 26, 2017 1.5 in Tri-clamp. Thanks, I'll take a look at that. Link to comment Share on other sites More sharing options...
indyspirits Posted January 26, 2017 Share Posted January 26, 2017 In the FWIW category, I've tasted many a bulk spirit that's been stored in HDPE totes with who-knows-what type of plastic valve and never have I picked up any plastic notes. On the other hand (and to answer your question), we use three-piece stainless valves with PTFE seals on our fermentation side and single-part on our "moving around spirits" side. EBay is your friend. 1 Link to comment Share on other sites More sharing options...
Southernhighlander Posted January 26, 2017 Share Posted January 26, 2017 We have sanitary ball valves and butterfly valves with PTFE seats. PTFE is impervious to ethanol meaning that it is impossible for it to import any flavor. You should never use a nylon seated valve with ethanol. Here is a link to our valves https://shop.distillery-equipment.com/collections/parts-and-replacement-parts/Valves We have quality valves with some of the best prices in the industry. 1 Link to comment Share on other sites More sharing options...
sailorman9 Posted January 27, 2017 Author Share Posted January 27, 2017 Would PTFE work for a hot vapor for a control valve on a still? Link to comment Share on other sites More sharing options...
