Teams already had access to the pool of valves you point out.
Limiting the Cv, but not limiting the number of valves allowed (It is allowed to hook up as many valves as you wish to a single actuator, this has been answered in Q&A) only punishes teams that can't afford a lot of valves, and those teams that have access to valves that would otherwise be legal.
The smaller Cv doesn't hurt us, but the $$$ we now have to spend to get legal valves does.

in 08 they did not limit cV but only limited you to the ones provided in the current KOP or previous years.

As we have found the old festo block has a Cv of .3 so it is good. So are you saying the SMC valve of 2008 had a .4 Cv? and if so were did you get this information from.
