T-Shirt cannon AC problem

[J@GMFlint]

Others are correct about applying DC to similar AC coils for light duty such as this application. My limited experience with my own irrigation system combined with the lower AC power ratings and my elect. background lead me to believe that we could safely try 12VDC before exploring 24 VAC power inversion options, and sure enough it works for our valves!

We use an off the shelf 1" rainbird valve, that looks very similar to what you have. I would suggest you simply remove the coil from your valve so that you can see the poppet and apply std. 12VDC. If the poppet retracts and holds you are good to go! A spike should work well to trigger the solenoid/valve. Put an ammeter on if you are concerned about the draw. For added comfort, since these were not rated for this particular duty, we do not leave the sols. energized for very long after each shot.
