Anyone have any idea what brand of 1.5 inch butterfly valves were used on the original morebeer conicals? I routinely disassemble my valve for cleaning and dont want to run into a situation where I damage it and have no replacement. I have wanted to order a new seat from Brewerygaskets.com, but even after breaking out the calipers I am unsure which one to get. The valve I have came with the fermenter and has 4 positions and the black ball on the end of the handle. I cant find any identifying marks on the valve or seat.
