HI Guys,

Thanks for the responses, I don't expect a sensor in the solenoid to tell me the exact percentage of the valve position but I would think that there would be something that with a certain voltage applied the solenoid would activate the valve to a certain position.

I'm sure with all the automation in larger commercial environment's and especially industrial that these would be common place. If I could find something that would do 25,50,75, 100 percent im sure it would be enough.
