Abstract

A hydraulic valve including a valve housing including a longitudinal axis, a receiving opening extending along the longitudinal axis, a first flow through opening of a supply connection, a second flow through opening of an operating connection, a third flow through opening of a tank connection, wherein the first flow through opening, the second flow through opening and the third flow through opening are configured at least partially flowable by a hydraulic fluid flowing through the valve housing, and a valve piston with a control groove which valve piston is axially displaceable in the valve housing in the receiving opening along the longitudinal axis, wherein the flow forces of the hydraulic fluid imparted upon the valve piston are oriented away from a first switching position of the hydraulic valve where the hydraulic fluid flows from the first flow through opening into the second flow through opening.
