Beverage dispensing unit for use in a beverage container filling arrangement, comprising: a beverage dispensing unit housing; a beverage container holder arranged to receive and hold a beverage container; and a cartridge for holding an outlet end of a disposable dispensing line, the cartridge being arranged to be releasably placed in a cartridge receptacle of a beverage dispensing unit, the cartridge comprising: a cartridge body, arranged to be connected to a beverage container filler, comprising a first dispensing line coupling element arranged to couple with the disposable dispensing line at a first position of the disposable dispensing line and a cartridge actuator mount for mounting an actuator module to the cartridge body; the cartridge further comprising an actuatable element, comprising a second dispensing line coupling element arranged to couple with the disposable dispensing line at a second position of the disposable dispensing line; the beverage dispensing unit further comprising: said cartridge receptacle for receiving at least part of said cartridge; an actuator module for actuating the actuatable element of the cartridge, the actuator module comprising: an actuator housing connectable to the cartridge; a force input for receiving an input force; a force output for exerting a force on the actuatable element of the cartridge; and a force transmission module for coupling the force input to the force output; wherein: the actuatable element is moveable relative to the cartridge body such that the second dispensing line coupling element is moveable relative to the first dispensing line coupling element between an open position and a closed position respectively corresponding to a dispensing state and a closed state of the disposable dispensing line; and the cartridge receptacle comprises a through-hole extending towards the beverage container holder. a beverage dispensing unit housing; a beverage container holder arranged to receive and hold a beverage container;
