So the bolt pushes down on the pin valve in the tank to release air which is then routed into the regulator. I'm debating whether to order the solenoid valve with expensive, 2 day shipping or not at this point. On one hand, I could rig up some kind of plunger to trigger the valve on the regulator and use that as a button and save 37 bucks... on the other hand, the plunger could fly out of my rig and kill someone... which would be bad...
