Valve does turn on every time

I have a system with 5 zones and 2 valve boxes. Zones 1 & 5 are in one box and zones 2,3 and 4 are in the other box. I am having an issue with the valve for zone 2. When the controller for zone 2 is turned on, I can hear the solenoid kick in every time, but sometimes the valve actually opens and sometimes it doesn't. If the valve opens there is plenty of pressure and all the heads work. If the valve doesn't open, then no water comes out at all (which makes sense).

I can also turn on the valve by manually turning the solenoid. Any suggestions about how to fix would be appreciated.

It's probably the diaphragm.
Do you know what model valve it is?
