cil,
When you use a 24 volts solendoid valve, the only legal and correct way to use it is to wire the solenoid module in the Crio for 24 volts. There is a wiring diagram on the First website to assist you. I believe you can find it in the KOP section. The Spike can only control 12 volts. While some people have reported that their 24 volt valves work on 12 volts, they are not reliable at that voltage.
