Update on my Brewie adventures, ran PBW through last night and was able to unclog the first hop tank. The other ones wouldn't budge and I ran water at them several times over the course of an 1.5-2 Hours. I was hoping the hot water and PBW would break them down but no luck.
Opened her up and found the silicone tubes and clamps to be an absolute pleasure to work with, absolutely love it. Got the first two taken off now as I write this and the second on is just jammed with wort. Not sure how it happened since I ran a full clean after. I will be taking the other two valves out and then get at the clamps as the hop tank inlet.
While I had it open, I decided to take a valve apart for the edification of myself and potentially the rest of the group if this hasn't been shared. I haven't found it anywhere but essentially the valves are pinch valves which is nice from a sanitary perspective. The good news is that you can get a 4 pack of the servos that drive these off of Amazon for 20 bucks. They are a MG996R, brand is towerpro in the Brewie but the model shouldn't matter (bad picture labelled Brewie Valve Servo). I'm unable to link, but search Amazon.
Installing a new one isn't as simple as just placing a new servo on and haphazardly installing the rotating "gear" portion (don't have a great name for it, see gray piece in Brewie Valve Gear in Correct Orientation Picture). I have not personally replaced any but the procedure I would go through is to remove the old servo and replace the new one. Do not reinstall the "gear" yet. Turn on the machine and close, then reopen the valve. Install the gear, making sure that the "gear" is pointing straight up (see picture reference above). I would then toggle that valve close/open again and see what it does. Based on that you can adjust and try again. You will want to get this part right otherwise your Brewie valve will not work. If not, the servo may work opposite, or only partially close/open which would not be fun.
The rotating part attached the the servo closes the other gray piece in picture labelled "Brewie Pinching Arm" that actually pinches against the silicone tubing. Hopefully this is helpful to someone. I believe all of the valves are the same so this should apply elsewhere in the machine, not just the hop valves. I'm going to continue my breakdown and will provide a final update. If anyone reads this in the meantime and wants more information, let me know and I will provide as best as I can while it is all apart.
