Hydraulic 2 way 12 volt 1/8 inch ball valve

I am looking for a hydraulic valve 3 waqy only an 1/8 inch .. I am designing a new prerotorator system for state of the art gyrocopter. I need an electric 12 volt activated throw valve that will linear move open one way then 12 volt move to the other line. It never has to be off but has to move so that the pressure can be switched from one 1/8 th inch line to the other ... must be small light weight and dependable..

thanks
