if they use a doubble-acting valve for the cylender and 2 single-acting valves to stop the exhaust they would fail open and allow the whole system to purge

Wouldn't that connect more than one valve to a cylinder input?
<R74> Each commanded motion of a pneumatic cylinder or rotary actuator must be accomplished via the flow of compressed air through only one approved pneumatic valve. Plumbing the outputs from multiple valves together into the same input on a pneumatic cylinder is prohibited.

32% of the teams in any division will be or could be in eliminations. And any one of those could be YOU. If you aren't ready, you will be eliminated. If you are ready, you greatly increase your chances of winning. - EricH [more]
