Atmos pneumatic valve use cases

[Changeling]

The other day I found an actual practical use case for the pneumatic valve. I'd welcome others share if they found any use of these obscure devices.

 

In the attached picture, you can see how to setup a pressure release vent, that vents excess pipe pressure.

Green square is the main pipe that you want to regulate.

Blue square pump rate setting indicates at how high pressure the valve opens. Other pump is set to 200 rate.

Red square is excess gas vent.

This contraption works by maintaining a fraction of main pipe gas inside the control input of the pneumatic valve. You can use this setup to make sure a TEG loop doesn't choke on too high pressure.

Smart stuff, I also agree that the pneumatic valve doesn't have a lot of use cases, but I guess you can make cool setups like this.
