In that case, the protip is keep some jewelers screwdrivers and light machine oil handy in the pit if you are using this type of valve and don't have sufficient budget to allow spares. Incorrect initial wiring seems to be the most pervasive problem with solenoid valves in the FRC context, but the second biggest issue seems to be debris getting into the valve causing it to get stuck in a fixed position. For all intents and purposes these valves can be fully disassembled and cleaned quickly if necessary, but only if you have those items handy. We've done it in less than five minutes-ish; not much longer than it would take to swap out the whole valve.
If my shop was snowed in and my unfinished robot was sitting in there, I'd dig it out with a plastic spoon or melt it out with a Bic lighter if I had to. Every hour counts. If there's a will, there's a way to make it happen. - sanddrag [more]
