制御弁。 A spool valve having a spool for controlling opening between these ports in a casing having two output ports, a supply port, and a tank port, and a spool drive means for applying a spool pressing force proportional to an input current value to the spool. and a pressure control valve including means for making the output pressure of an output port counteract the spool pressing force via a spool, wherein the spool driving means is a single torque motor, and an output shaft of the torque motor is connected to the spool. A pressure control valve comprising a cam mechanism connected to each other and proportional to the spool stroke required for pressure regulation of two output ports and the rotation angle of the output shaft of a torque motor.
