Hi Timmy,
were you able to make it work?
I have a similar solenoid, but it is a DC latching type, normally works with 9V battery. It turns ON the valve if voltage is applied in one direction and the valve is turned off when the voltage is applied in reverse – and that’s likely the different in my case.
The nice thing about it the voltage has to be applied for only a few milli-seconds (30-50ms) and otherwise no more power is needed to keep the valve ON.
I assume your solenoids are DC, but not of a latching type.
