Abstract:
The purpose of the present invention is to increase noise performance of an electric valve having a communication function. An electric valve (10) comprising: a motor (12); a power transmission mechanism (14) for converting rotary motion generated by the motor (12) into the axial motion of a valve body; a housing (16) that receives the motor and at least a part of the power transmission mechanism (14); an external connector (18) which is provided to the housing (16) and which enables power supply to the motor (12) and communication with a control device connected through a network; and a control board (41, 42, 43) which is provided inside the housing (16), which processes the communication, and controls the motor (12), and in which a connection position to an external-connector-side terminal (18B) and a connection position to a motor-side terminal (12B) are located on the opposite sides to each other with respect to the axis (L) of the motor (12).
