At the Buckeye Regional we went through three (3!) brand new, in-the-box Festo valves and did not find a single one that worked. We had good LED indications, and sufficient pilot valve pressure, but we never got a single stroke out of them. I'm confident it wasn't user error - our 2007 KOP Festo worked just fine in the same installation. If it weren't for a more favorable Cv from the Festo, we'd have gone right to the SMC valves in the initial design. Ultimately that's what we wound up doing anyhow. In the future we'll just save ourselves the hassle and go right to the SMC.
