6 prong is basically 2 3prongs in 1 housing, the terminals are not connected in the switch. If you want run 2 valves on 1 switch it has to be at least 6prong, 4 valves 12prong. For what you want to do you need 2 6prong & 1 12prong. You have to wire all the power in (center) terminals together, but all of the power out have to be seperate.
