Provided is a fast switching hydraulic pilot valve with hydraulic feedback for quickly and accurately switching between opened and closed positions of the hydraulic valve. The hydraulic valve includes a valve body, a valve bore defined by the valve body, a plurality of valve ports extending through the valve body and into the valve bore, and an actuator. Actuation of the actuator allows for movement of the spool to a first position within the valve bore, thereby providing for one of opening or closing the hydraulic valve. Exposure of the spool to a pressure at an end of the spool proximate the actuator allows for movement of the spool to a second position within the valve bore, thereby providing for the other of opening or closing the hydraulic valve.
