It seems that my drawing did not load properly, not sure what's going on there. Here it is again:

Where is shows a manual valve just substitute solenoid valve, the dump valve is a quick exhaust, and where it shows a PUMP, think flow control.



The amazon link above seems to work for me. https://www.amazon.com/s?k=air+quick...ref=nb_sb_noss

If not just go to amazon and search air quick exhaust

If you don't dump the air on the tank it will continue to flow until it runs out of air, and that could take a while

I am using a 3 port valve with a splitter or Tee, I don't remember which. Either way from an air flow perspective it's the same.
