Only half of a zone is working

I am a homeowner with a 15 zone six heads per zone homeowner with an odd issue. I have one zone that recently stopped working on 3 of the 6 sprinkler heads. I don't see any evidence of breaks in the lines and even when I manually activate the valve there is no change. All other zones work properly. Any ideas? :)

I think I have seen this before

I think I know what this is.
Either at the irrigation controller or in the field, There are two independent valves that are wired together. So, When the timer activates the designated zone valve at the controller, actually 2 solenoids are activating.

Either you have a electrical issue wiring or Solenoid on 1 of the 2 zones that are wired together. Or, a problem with the diaphragm on 1 of the 2 zones wired together.

Good Luck
