Abstract: A filler element includes a valve arrangement that switches it between filling mode and CIP mode by controlling a connection between a chamber formed in a housing and a CIP channel formed from a valve body provided at a filling-height-controlling element. Axial movement of a filling-height-controlling element through an extension connected to the chamber controls mode-switching. In both modes, a continuous fluid connection exists between the extension's CIP connection and the CIP channel. Axial movement of the filling-height-controlling element also controls filling height in the container. In CIP mode, a CIP flow formed in the housing conducts liquid CIP medium out of the boiler, through the filling element, and out into a CIP channel.
