Condensate drain valve for arrangement in a valve mounting of a sterile container that can be closed in a gastight manner, comprising - a valve housing, which has at least one inlet portion, which is opened/openable towards a container gas volume enclosed by the sterile container, and at least one outlet portion, which is opened/openable towards an external gas volume that at least partially surrounds the sterile container, - a bypass, by means of which the inlet portion and the outlet portion are connected/connectable to one another in at least gas and/or fluid conducting fashion by means of a bypass gas volume that is partially enclosed by the bypass, and the bypass gas volume is always in operative connection with at least the container gas volume or the external gas volume, - a valve body which can be displaced between a blocking position and a passage position and by means of which, in its blocking position, a condensate outlet of the sterile container arranged in the valve mounting is closeable/closed and - at least one actuator associated with the valve body and at least partially surrounded by the bypass gas volume, by means of which the valve body is displaced/displaceable between the blocking position and the passage position depending on a temperature and/or a pressure of the bypass gas volume, characterised in that - the valve housing has at least one retaining bar and at least one closure means spaced apart from the retaining bar, wherein the retaining bar can be arranged/is arranged at least partially in a retaining lug of the valve mounting and the valve housing can be fixed/is fixed to the valve mounting so as to be pivotable about a pivot axis aligned parallel to the retaining bar, - the valve housing can be pivoted about the pivot axis from an open position to an installation position in which the closure means is fixed/can be fixed to a closure mounting of the sterile container, - with the valve housing transferred to the installation position, the valve body is transferred to the blocking position by the actuator fixed to an actuator mounting of the valve housing and is subjected to a closing force, and - the valve body is transferred to the open position by the actuator as soon as the bypass gas volume has an opening pressure and/or an opening temperature, so that an exchange of medium between the container gas volume and the outer gas volume is made possible. - a valve housing, which has at least one inlet portion, which is opened/openable towards a container gas volume enclosed by the sterile container, and at least one outlet portion, which is opened/openable towards an external gas volume that at least partially surrounds the sterile container, - a bypass, by means of which the inlet portion and the outlet portion are connected/connectable to one another in at least gas and/or fluid conducting fashion by means of a bypass gas volume that is partially enclosed by the bypass, and the bypass gas volume is always in operative connection with at least the container gas volume or the external gas volume, - a valve body which can be displaced between a blocking position and a passage position and by means of which, in its blocking position, a condensate outlet of the sterile container arranged in the valve mounting is closeable/closed and - at least one actuator associated with the valve body and at least partially surrounded by the bypass gas volume, by means of which the valve body is displaced/displaceable between the blocking position and the passage position depending on a temperature and/or a pressure of the bypass gas volume, - the valve housing has at least one retaining bar and at least one closure means spaced apart from the retaining bar, wherein the retaining bar can be arranged/is arranged at least partially in a retaining lug of the valve mounting and the valve housing can be fixed/is fixed to the valve mounting so as to be pivotable about a pivot axis aligned parallel to the retaining bar, - the valve housing can be pivoted about the pivot axis from an open position to an installation position in which the closure means is fixed/can be fixed to a closure mounting of the sterile container, - with the valve housing transferred to the installation position, the valve body is transferred to the blocking position by the actuator fixed to an actuator mounting of the valve housing and is subjected to a closing force, and - the valve body is transferred to the open position by the actuator as soon as the bypass gas volume has an opening pressure and/or an opening temperature, so that an exchange of medium between the container gas volume and the outer gas volume is made possible.
