Two regulators for one piston

I think your original post is legal, but Al is the CD rules guru (and a good one at that). Given the uniqueness of this, you may want to submit an official Q&A.

The way I interpret your question is:

-------------- portA
|
-
valve |
-
|
----2nd Reg -- portB

you only have one valve and its outputs are not connected together (other than through the piston, which is typical). So the real question is can you have a regulator after a valve (or can you have two working pressures). I don't see a rule that prevents this - and it should help you exhaust the air out of portB quicker.
