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. |
R77 is a little ambiguous when it comes to quick exhaust valves. A reasonable read of R77-H would allow them. R77-G specifically allows check valves as long as the high pressure vent will complete exhaust the system.
As an inspector, absent guidance from my LRI, I would allow them.
