Finally after a day or two we decided to go back to our 12v, and found that it wouldnt work as well. We have NO clue as to why. All of us have little experience with this issue and with pneumatics in general. The solenoids are receiving power but the valve isnt turning on or off.

Is the system pressurized while you are testing the valves? The valves we use generally have a minimum PSI needed to switch, this includes the outputs of valve. If an output is venting to the room, the valve will not switch.

Also, how did you verify that the valve was receiving power?
