1. Get the highest Cv flow valves you can get. KOP ones are about .25Cv, you can find others that are higher, we found some that were .8Cv, makes a big difference.
2. Mount solenoid valves with a double male nipple directly to the piston if you have the room. No using tubing is huge as well between solenoid and piston.
3. Next create a low pressure (60) reservior (tank) right before the solenoid with no elbow fittings and use the shortest length of tubing as possible. Length is bad, avoid length.
That should help
remember the solenoid (valve) openings must be 1/8" as per rules and must be able to operate at 120psi, Cv can be high as you can get....
