The invention relates to a ball valve having a housing made of plastic in which a carrier structure is disposed that is encased in plastic in which a valve ball having a through opening is pivotally supported between an opening and closing position, said carrier structure comprising two carrier rings positioned opposite each other, and a connecting element connecting said carrier rings. In order to create a ball valve made of plastic that is characterized by a simple construction and improved impermeability, the invention provides for the carrier structure to separate the valve ball completely from the plastic of the housing.
