These don't pass R66, unless we ignore the parenthetical "(specifically "needle valves")". I wanted to use some last year and was shot down by the GDC:

Q34
Q.Is a quick release valve, such as the one sold by Bimba (part number 1BQEV), considered a flow control valve, and thus a legal pneumatic component per Rule 77 (F)?
A.Quick Exhaust Valves are not included on the list of permitted items in R77.

R77(F) is largely identical to this year's R66(F) except for this year's addition of "passive" and the parenthetical. So unless the GDC's interpretation has greatly changed, quick exhaust valves were illegal this year.

Mind you, I'd love if they were legal for the obvious speed increases. So if you're petitioning the GDC to update the regulator part of R66, you might want to add that as well.
