Not to rain on anyone's parade..........

This valve's main purpose is to "Dump" air pressure quickly in the event of some emergency (like the main breaker for your pneumatics). If you have this thing embedded in some other device, you obviously will not be able to access it. It's suppost to be located in a place that can be accessed quickly (again, like the main breaker).

Hint:
I would not pass this thing in tech inspection.
