Need help troubleshooting irrigation system

Stockton, CA

Looking for info on figuring out why these valves are not working. Not sure what the round knob is for since it doesn't make any difference whether it is opened (turned counterclockwise) or the closed the other way. The solenoid valves are sitting freely and can be turned without much effort.
I've tried manually turning the valves on to see which zone is serviced by each to no avail.
