I have 3 stainless steel fermenters (7 gallons each). I replaced the original ball valves that came with the fermenters with 3 piece sanitary ball valves. However, after 2 back-to-back infections, I realized that I needed to take apart the ball valves and soak them each time (note the infection did not come from the valves, but better safe than sorry). While the ball valves worked fine, I did have trouble dumping the trub on certain batches given the diameter of the bottom ball valves. I thought about replacing the ball valves with butterfly valves, but they were too expensive and I did not see a need. When I saw the price on these, I thought I would given them a try. I am glad I did.They are nicely built and are very beefy and heavy. They made dumping trub easier given their interior diameter (1 1/2"). In addition, they are very easy to clean. No more need to take the valve apart to soak it in PBW. The only downside I have found is that it more difficult to control the flow of liquid than the ball valves. However, I knew that going in and this does not create any problems for me.Overall, I am very happy I made the switch.
