This is not the case...if using an off-board compressor AND you're storing high-pressure air, you need an additional relief valve.

I'll copy-n-paste R86 again, this time with emphasis: The relief valve must be attached directly to the compressor or attached by legal fittings connected to the compressor output port. If using an off-board compressor, an additional relief valve must be included in the high pressure side of the pneumatic circuit on the ROBOT.

Do make sure you follow stinglikeabee's advice about the T-fitting if you're using a new compressor. You can't have any tubing between the compressor & the attached relief valve; this was a common problem in Hub City that caused 8 or 10 teams to re-work their pneumatics before getting their inspection sticker.

Thanks for the clarification. I misread it as "release"
