PROBLEM TO BE SOLVED: To provide a pilot type selector valve for enhancing responsiveness while preventing hunting of a main spool. SOLUTION: For solving the problem, this invention has a pilot chamber 24 faced with the spool 22, a pilot passage 30 for introducing pilot pressure to this pilot chamber 24, a pressure reducing valve 26 for generating the pilot pressure and a proportional solenoid 25 for controlling this pressure reducing valve 26, and is characterized by arranging two or more orifices 31 and 32 in series in the pilot passage 30 and arranging a chamber 35 between the orifices 31 and 32.
