We're adding a pneumatic system to our robot and though we're not happy now, but we hope it'll make us happy later. I haven't worked with pneumatics in years, so my knowledge is a bit rusty, but I have to have a drawing ready for our laser cutter by this evening, so I'm trying to lay out the plumbing right now.

The rules say that we have to have pressure gauges that display both working and stored pressure. Presumably, the pressure regulator displays working pressure and I need to add the second pressure gauge to the system before the regulator. The schematic in the pneumatics manual supports this.

Is that correct?

Also -- there's some chance we'll leave the compressor offboard. How do I manage that connection such that the air doesn't leak out of the system when the compressor is disconnected? The check valve seems to be the answer there, but it's not mentioned in this year's manual, so I'm not sure if we have any around.

Thanks!
