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