ABSTRACT:
A valve for sterile sampling of a liquid sample from a container includes a valve body (1) with a valve chamber (2). The valve includes a sample inlet (6) in the valve chamber (2), a first valve seat (7), a first valve plug (5a) for closing the sample inlet (6) through abutment against a first valve seat (7), an outlet (8) from the valve chamber (2), a cleaning inlet (9) in the valve chamber (2) for disinfection fluid, a second valve seat (10) and a second valve plug (5b). The outlet (8) is positioned between the two valve seats (7, 10), and the second valve seat (10) and the second valve plug (5b) are positioned in such a manner that the second valve plug (5b) through abutment against the second valve seat (10) cuts off the inflow of disinfection fluid in an area (2b) of the valve chamber (2) at the sample inlet (6).
