Not sure what a POV solenoid is. But you are talking about the Festo First Choice solenoid that has two solenoids on it... As for as the electrics & programing are concerned, it is two separate solenoids. First make sure of the voltage. Current 2013 year is 24VDC. Wire your solenoid valve breakout for 24 V.
You power one side at a time & the valve shifts in that direction & stays there until the other side is energized. (bistable operation) You only have to energize the solenoid for a fraction of a second for it to operate. It does not hurt to energize it continually, but only energize one side at a time.

There is a manual button next to the solenoid plug. You can use it to see what side does what.
