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