A quick exhaust valve is an assembly of parts, one of which is a check valve, but while it contains a check valve, it is not a check valve, any more than a pneumatic cylinder is a piston, or a car is a transmission.

I am an LRI and I'm saying that R77 G was put in place to allow quick exhaust valves. I agree the wording isn't perfect but that was the intent of the rule to my knowledge and how I will be enforcing it.
