I hope that the documentation provided by Gary is sufficient. It says that the the valve will not fail catastrophically at 125 PSI, it does not say that the valve is
RATED at 125 PSI. The rule says: (emphasis mine)
Quote:
All included items must be “off the shelf” pneumatic devices rated by their manufacturers for pressure of at least 125psi, and...
...Solenoid valves that are rated for a maximum pressure that is less than 125psi rating mandated above are permitted, however if employed, an additional pressure relief valve must be added to the low pressure side of the main regulator. The additional relief valve must be set to a lower pressure than the maximum pressure rating for the solenoid valve.

By the letter of the rule, if your valve is not rated for 125 PSI (any SMC valve w/o a K in the part number is generally rated at 100 PSI) you must install a regulator to reduce the pressure to below the valves rating. Since the maximum allowable working pressure is 60 PSI, you should be OK, but they could require a second regulator downstream of the first for redundancy.
It also kind of irritates me that we paid extra ($$$) and waited an extra 2 weeks to get a special version that is rated above 125 PSI so that we would be legal, and it may be unnecessary. This is a catalog option that is available to all teams, anyone could have ordered it.
