Re: R07-100-RNEA regulator outlet pressure

Maybe instead of playing with the storage pressure rules, we could take a rule staring from the rulebook and suggest it be adapted for other items. R66 D states "Solenoid valves that are rated for a maximum working pressure that is less than 125 psi rating mandated above are permitted, however if employed, an additional pressure relief valve must be added to the low pressure side of the main regulator. The additional relief valve must be set to a lower pressure than the maximum pressure rating for the solenoid valve,"

Why limit that just to solenoid valves (other than the fact the rules have that limit imposed)?. Do some research. Find the difference in available selection for the rotary pneumatic actuators you describe, sorted into "legal" and "illegal", and if you can, suggest that this rule be extended to include those actuators as well. The presence of an additional relief valve could very easily be argued to make these actuators safe for use, I would think, and if a team isn't using them then it won't affect them.
