Abstract: An electrically drivable valve for regulating volume flows in a heating and/or cooling system of a motor vehicle with a housing, on which at least two connecting pieces are formed, whereby depending on the arrangement of the valve in a heating and/or cooling circuit one or more connecting pieces are formed as inflow connections and a connecting piece as an outflow connection or one or more connecting pieces as outflow connections and a connecting piece as an inflow connection, whereby a valve body rotatable around a rotation axis is arranged in the housing. In the case of an electrically controllable valve, in which pressure losses in the control circuit are reliably reduced, in the case of an axial inflow or outflow of the valve by a heating medium and/or coolant the axes of one or more outflow connections or of one or more inflow connections are oriented axially and radially relative to the rotation axis of the valve body.
