If using these, just remember that you still must meet R89:

If the compressor is not used on the ROBOT, then an additional pressure vent plug must be connected to the high-pressure portion of the pneumatic circuit off-board the ROBOT with the
compressor (see R80).

Does anyone have an example of a useful application for the 3-way exhaust valve?
