Also R82 refers to a "single primary adjustable, relieving, pressure regulator". It does not say how it must be adjusted.
I'm not arguing the point, just trying to understand the scope of the applicable rules. Maybe it is worth a GDC query.

If the GDC bothers to read a datasheet on the EPP4, they might get a little nervous:

Safety position:
In case of control signal failure or if it is less than 50 mV, the regulated pressure drops automatically to 0 bar (atmospheric pressure).
In case of voltage supply failure, the regulated pressure will be kept constant

(EDITED this section, regulators does actually keep regulating...) Lose power to your robot and your regulator stops adjusting. Mechanical regulators stay where you put them, but I'd be worried about control transients and oddities with that electrical one.
Reading through that, you're also going to have a fun boot-up. Lost control signal means it drops the regulated pressure to 0, so your system is going to be unpressurized while the roboRIO is booting.
I can see some uses for regulating catapult power and such, I think 488 effectively made an exploded version of this for their catapult in 2012, but I don't think it should pass muster for a main regulator.
