Pneumatics R88 Question

[FRC8]

Rule R88 in the pneumatics section states:

There is no limit to the number of solenoid valves, pressure regulators, pressure gauges, and connecting fittings that may be used on the ROBOT.

Does this statement include the Norgren pressure regulator that acts as the primary regulator. More specifically, are we allowed to have a system with one compressor and one set of air storage tanks that feed two of the Norgren primary pressure regulators. The effect is to have two independent working air systems feed by a single air supply system.

[GDC]

As long as the regulators are configured in a manner consistent with all pneumatic rules (in particular, Rule <R98>), then there is nothing that would prohibit using multiple Norgren regulators. But please note that under Rule <R98>, and for the purposes of a predictable and reasonable inspection process, there is to be only one primary regulator connecting the "high pressure" part of the pneumatic system with the "working pressure" part of the system. Any additional regulators (Norgren or otherwise) supplying branch circuits of the system must be located downstream of the primary regulator.

(edited to clarify a possible misinterpretation that could appear to be in conflict with the rules)
