The invention provides a valve ( 1 ) for sterile transfer of fluids. The valve ( 1 ) comprises a housing ( 5 ) having first and second open ends ( 2, 3 ) and a passageway ( 4 ) extending between the ends ( 2, 3 ). The first end ( 2 ) has a flange ( 54 ) for coupling the housing ( 5 ) about an opening ( 205 ) of an external conduit ( 201 ) and a seal blocking an open area of the first end ( 2 ). The seal is placed in register with the opening ( 205 ) of the external conduit ( 201 ). The valve ( 1 ) has a piston ( 9 ) movably disposed within the housing ( 5 ) so as to interrupt the seal and to permit fluid to pass along the passageway ( 4 ). A mating surface ( 215 ) of the flange ( 54 ) and the seal form a sterilisable surface. The seal is formed between a plastic plug ( 18 ) movable by the piston ( 9 ) and a sharp plastics rim ( 15 ) which encompasses the open area of a first end ( 16 ) of the housing ( 5 ).
