I have seen these valves a few times and the Orbit water valve you have operates on 24 volts DC. The standard irrigation controllers and valves operate on 24 volts AC. Your valves operate by applying +24v to open the valve, and -24v to close the valve. It uses a latch solenoid, drawing power only when you open or close it and it just needs power for a fraction of a second. You cannot apply continuous power to the valve because it will smoke in a few seconds and burn out. Because of the voltage and operational differences of your valves, I believe they will not work with the Iro.
