This should do it.

Mrfixit,
Just so I understand, what is the process to fix it? Do I just open it up and change out parts? I have never seen the inside of a sprinkler valve so I am sure that I am making myself believe it is harder than it actually is. I just want to make sure that I have as complete a picture as I can before I start down the path.
Thanks for the help!
