A kind of superhigh pressure digital directional valve was designed. Motor instead of electromagnet was not affected by the polarization time. The rotation feed movement of the screw was used to replace the linear sliding movement of traditional directional valve core. The valve core spiral feed movement is better than the linear sliding of traditional which was not easily jammed and had strong ability to resist pollution. The valve sleeve structure was added, to avoid the whole body was made with precious metal materials of high hardness, so the cost was saved.
