I did disassemble and clean the old valve, however I did not test it to see if I fixed it. It’s easy to take apart and clean the surfaces, it would not take much to foul up a seal and there was some grit inside when I took it apart.
Most of the sprinkler control valves are now 24v instead of 12v so they can be harder to find.
Here are the photos of how it comes apart and goes back together
