Steve, I have a different opinion of the function of that device .
I think if you look closely you will see it is an air regulator with the output to atmosphere .
It should be adjusted to relieve pressure above normal cut out for the engine compressor .
In this way it provides a safety release for anything that can overpressure the air system In your coach.
I have noticed that once you exceed normal air pressure and this regulator relieves, it does not want to seat well and may leak .
