Re: Run with solenoids from a spike
 

Spring return pneumatic solenoid valves are legal. They are in the 2012 kit of parts (first choice). If they are energized when the match end (robot disables) They will return to the d energized position. The cylinder they are plumbed to will also return to its disabled position. One side of the cylinder will have pressure on it. This is legal. Don't over think this.
