| description | Provided is an electrically operated valve that can be assembled at a low price in a short time and that can suppress wear during operation. The electric valve comprises a valve shaft which is driven by a motor to rotate and moves in the axial direction; a valve body unit provided with a valve seat and rotatably holding the valve shaft; a valve body disposed so as to be displaceable in the axial direction with respect to the valve shaft and seated on or separated from the valve seat; a valve holder that moves together with the valve shaft in the axial direction and holds the valve body; a spring member that generates an acting force in a direction in which the valve shaft is separated from the valve body; and a spring stopper fixed to the valve holder so as to be disposed between the valve shaft and the valve body. The spring stopper is positioned in the axial direction with respect to the valve holder in a manner such that a first axial direction position of the valve shaft, which includes at least a fully c |
