I was wondering if we could still use the solenoids from last year? I did not see anything against them in the rules so I am just making sure.
If we are, does anyone know where I can get the proper documentation to show to prove that they are legal at the competition?
Thanks.

Do you mean the solenoids that were about the size of a deck of cards (Festo brand I think)?

I hope so because my team is using them (or planning on using them).

On the subject of those solenoids, does anyone have a link to a spec for them? I have been told that they used 12V but I would feel better if I saw it in writing. There is also that matter of "125 psi rating" from the rules that we have to deal with.

Joe,
Simple answer is yes.

<R33> COTS items from ROBOTS entered in previous FIRST competitions or COTS items that are no longer commercially available may be used under the following conditions:
A. The item must be functionally equivalent to the original condition as delivered from the VENDOR (e.g. a part that has non-functional label markings added would be permitted, but a part that has device-specific mounting holes added would be prohibited), and
B. The item must satisfy ALL applicable 2010 FRC materials/parts use rules.

2009 Festo KOP solenoid (http://www.team358.org/files/pneumatic/FestoFIRST_Instructions.pdf)

I had a better spec around here somewhere, but I don't know what I did with it...

Joe, make sure you have spares. Of the six I've checked out from prior years, 2 had internal leaks, either through the exhaust port, or they bled air between ports. Also, although they look the same, at some point there was a change in wiring, we had both types, A & B.
