Okay, Thank you everyone.

We are using festo solenoids, ours say, 12/24 volts on them so I guess we can use whatever voltage we want. I can hear mine fire even without pressure. Perhaps they work under 20 PSI like someone said.

We decided to just place a regulator after one the of the values. We lowered the PSI to 45 PSI.

The change in 15 PSI really helped.

Thank you everyone. Now theres just one more problem, but I will start new thread for that one.
