An electric exhaust gas recirculation valve for an internal combustion engine. The valve having a body structure, an entrance at which engine exhaust gas to be recirculated enters the body structure, a passage that extends through the body structure for conveying engine exhaust gas that has entered the entrance, an exit at which engine exhaust gas that has passed through the passage exits the body structure, a valve mechanism having a valve member with a head, and a stem disposed within the body structure and comprising an armature that engages the stem at a single load operative connection for operating the valve mechanism.
