How come my valves to my sprinkler system only turn 1/4 of a turn?

I have a sprinkler system that is into its second year. It was professionally installed by a licensed contractor. The water system that he tapped into was put in place by Lewis Homes. I tried to turn on the sprinkler system after the winter, but I could only turn either valve 1/4 turn. My guess would be that they got some mud in them and won't turn any further. Does anybody have any advice for how to fix this? The biggest problem is that they are about 5 feet under ground, though surrounded with PVC pipe.
