remote valve

I am searching for a remote valve that can fit my specific requirements. After careful consideration, I have selected a servo remote valve for this project. The desired voltage for the valve is 12V, and it will be used for a water system application. the valve is a 180 degree GF ball valve for bleach mixing. the valve needs to be able to be open from 0-100% and stop in any position along the way. The valve is attached as a picture.
