While a quick exhaust valve has a check valve in it, I would not refer the assembly as a check valve. Anymore than I would call a cylinder flow control valve a check valve although they generally have a check valve in them. Anyway. Intended or not, the way I read the rule is you can use check valves. Check valves have to be used in such a way the R89 is met & the system can be fully vented by the one vent valve. One application would be to vent closed ended portions of the system.
Team update 15 spefically amended rule 77-G to add quick exhaust valves to the allowed list.
Now that I think about it a bit... A quick exhaust is essentially a pilot operated check valve. Given the GDCs dislike of pilot operated valves, I am not sure I would ask a question to them calling it that.
