SE Nebraska | I have 2 of these banjo ball valves on the fertilizer pump on my planter. They either supply fertilizer or shut off and then bypass the fertilizer back through the pump. This is on a Deere planter and I am running it on a case in tractor. In order to control them they must all be controlled by a Deere controller so that is not an option for me. I am going to make a simple 2 switch box so that I can shut each valve off. I don't understand the wiring diagram on the side of the valve. My plan was just to have an on/off switch, but will that work the way the diagram shows. Do I need a 3 position switch, power open/ power close/ and a middle position that doesn't do anything?
Edit to add: There are 3 wires on each valve red white and black.
