If it is an irritrol 2400T thats easy to fix. Go online to sprinklerwarehouse and buy on. When it comes unsrew the bonnet. (Grey Ring) and pull out all the insides and top including the black ring. Then bring that outside to the bad valve. Unscrew the bad valve and then put in the new valve, into the old body (before putting the new guts in flush the valve. Also shut off the water before doing this) Then scew the bonnet on nice and tight, re wire, and turn on the water. If that dosnt work check your timer and wiring. HOpe that helps. Where are you located?
