並設せしめてなる電動比例弁。 A ball valve that pivots with a vertical pivot axis is provided in a valve box that has an inlet pipe on one side and an outlet pipe on the bottom side, and this ball valve has a center hole and an inlet of the valve box. A valve hole extending in a direction perpendicular to the pivot axis that communicates the flow path on the pipe side, and a discharge hole along the pivot axis that communicates the center hole with the outlet pipe side of the valve box, and a pivot connected to the ball valve. In electric proportional valves, the shaft is connected to a drive unit operated by a motor mounted on the outside of the valve box, and the motor is controlled by electrical signals of external conditions such as temperature, pressure, humidity, etc., and the rotation provided on the ball valve. An electric proportional valve in which a valve hole perpendicular to the axis is divided into a plurality of valve holes having different diameters, and these valve holes are arranged in parallel at intervals in the rotation direction of the ball valve.
