I think the brass one I was looking at was a 120v solenoid and I didn’t realize that while looking. I wonder if the threads on that solenoid are the same as the 24v ones and if  you could replace it with a standard 24v solenoid?

In looking around I did notice that one of the dealers on Amazon was having a sale on some on their own website. These normally $155 dollar ones are on sale for $45. I have no idea if they are any good or if they are discontinued or if they simply don’t pass enough water but it might be worth picking up one to experiment with, or perhaps a case of them at that price ;)

The $80 version I was looking at on Amazon is here:

but again I have no idea if thats any good. For between 45 and 60 bucks or so you can get actuated ball valves which have a better flow rate than the solenoid valves. But they are controlled on or off by sending the power and then reversing the polarity, or powering to separate wires to turn them off again. That is not that big of a deal if you’re rolling your own controller ;) But would not be compatible with a commercial irrigation controller without doing some futzing around.
