No Water In Valves

My sprinkler box opens and closes the values properly in each zone, but no water is getting to the valves. There is plenty of water pressure at the backflow preventer, but still no water getting to the valves. The only thing I can think of is there is a block somewhere between the water supply and the valves. Everything was working fine a couple weeks ago and now nothing. Any ideas?

Could be a master valve that doesn't come on.

Could be a valve has been shut off after your backflow device. Ball valve or gate valve.

A broken pressure regulator can cause a very low water flow.

You were right. It was the master valve. We just moved in and I didn't realize there was one on the system. Thanks.
