Alcohol Storage Tank Valve

Recommended Posts

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?

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.

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.
