I’m not sure where you get your information about the solenoid valves not working below 30psi. From my experience, they will still fire fine even with no air in the system. I would recommend trying to just regulate down to 30psi first. That being said, I dont believe that there is anything prohibiting regulating the output of the valve.
I thought I remembered reading somewhere that the solenoids won’t operate below 30 PSI.
We are using Pneumatics to pick up our ball and load it onto our shooter. As of right now, 60 PSI is way too much for this. We have a two different pistons controlling X and Y axises. The X squeezes the ball and the Y loads it onto the shooter.
Y piston comes back to hard and hits our mechanism hard. (We don’t mind it hitting the mechanism, just not so hard)
We haven’t tested X yet but i’m hoping it doesn’t squeeze the ball too hard at that pressure.
We have another piston but that one is doing good at 60 PSI.
I believe it is 11 inches while intruded. But it stretches the length of the mechanism so changing the size of it will change other factors and we will need to add other things to get the size right. I would prefer this solution as my last resort.
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.
Older-style Festo solenoids only require about 17 PSI to fire. If you can deal with a lower co-efficient of flow, I’d recommend Humphrey 310 or 410 series solenoids. They can run on anything above 14 PSI. Getting a narrower cylinder is a good idea as well, we have a few Clippard cylinders with a 3/8ths inch bore. This will give you about 6 lb of force on the output
