Abstract

[Object] To provide a motor-operated valve that is easy to assemble and allows the position of a valve member to be detected more accurately. [Solution] A motor-operated valve 1 includes a valve body 10, a can 30, a driving shaft 70, a planetary gear mechanism 60 that transmits the rotation of a rotor 51 to the driving shaft 70, a valve member 40 that is disposed in a valve chamber 13 of the valve body 10 and changes in position in an up-and-down direction in response to the rotation of the driving shaft 70, and a magnetic sensor 85 that is disposed outside the can 30. The motor-operated valve 1 includes a driving magnet 76 that is mounted on the driving shaft 70 and rotates together with the driving shaft 70, and a driven magnet 77 that has a circular annular shape and encloses the driving magnet 76. The driven magnet 77 rotates about the driving shaft 70 in response to the rotation of the driving magnet 76. The magnetic sensor 85 detects magnetism of the driven magnet 77.
