I'm talking about the relief valve (the one with the blue spring inside it).

EDIT

Or did you mean the black manual valve?

And what about the so called relief valve on the KOP checklist?

The "relief valve" from the checklist is the one that you cannot change. It must go on the compressor. <R95>.

The black manual valve also must be in the system.

<R97> The Parker pressure vent valve must be connected to the pneumatic circuit such that, when manually operated, it will vent to the atmosphere to relieve all stored pressure. The valve must be placed on the ROBOT so that it is visible and easily accessible.

I don't know which relief valve has a blue spring inside it. Might be one of the regulators or gauges.
