An electromechanical converter of threeway 2D digital servo valve was designed in order to improve the transmission mechanism and zeroposition holding mechanism. This improved converter was made the valve spool circumrotate accurately through the stepper motor and keep the valve spool at the prescriptive zeroposition in the axial and radial direction. The experimental results show that the improved converter can meet the requirement of 2D digital servo valve.
