サーボ弁。 Generated by the fluid passing through the spool valve in a servo valve that controls the flow rate of fluid, which is composed of a valve part consisting of a spool, sleeve, and valve body, and a force motor consisting of a coil, coil bobbin, and magnetic circuit that directly drives the spool. A servo valve for compensating fluid axial force, characterized in that it is provided with an electrostrictive element that generates a force equivalent to the fluid axial force by a command voltage in a direction opposite to the fluid axial force that acts in the direction of closing a spool valve.
