Programming a Spike connected to a dual solenoid valve this way is pretty simple. Set the Spike to "Forward" and the solenoid valve will switch one way; set the Spike to "Reverse" and the solenoid valve will switch the other way. Setting the Spike "Off" will let the solenoid valve hold its last commanded position without using extra electrical power, but the necessary power is very small and every solenoid valve I've seen used in FRC is able to handle continuous current.
Don't set both halves of the Spike on at the same time. The solenoid valve will get confused and not know which way to switch. Any particular one will probably pick the same way every time, but different ones can act differently.
