Valve apparatus, arrangement with valve apparatus and method for operating arrangement

The invention relates to a valve apparatus having a housing (100). The housing has a first port (102) and a second port (106). The first port is connected to a tank (200) and has a closing element (110). The closing element is provided in the housing and which can be placed into an open position where a fluid connection is produced between the first port and second port, and can be placed into a closed position where the first and second ports are separated from one another in fluid-tight fashion. First (120) and second (130) seal arrangements are provided between the closing element and the housing, wherein the first and second seal arrangement (120, 130) are spaced apart from one another and each seal arrangement interacts with a corresponding seat (126, 136). To create a valve device for the aseptic transport of filling material, a chamber (140) is provided and is defined by the seal arrangements, the closing element and the housing in the closed position, a reservoir (142) is provided which can be connected to the chamber and which serves to accommodate a bactericidal fluid, and the chamber (140) and the reservoir (142) are adapted to form a germ barrier that is created in the closed position with the bactericidal fluid. The invention also relates to an arrangement having the valve apparatus and to a method for operating the arrangement.
