2. The sanitary valve ( 1 ) as claimed in claim 1 , further comprising at least one of a mouthpiece securing means ( 11 ) or a jet regulator securing means assigned to an outflow opening ( 10 ) of the valve housing ( 3 ) formed on the valve housing ( 3 ).

3. The sanitary valve ( 1 ) as claimed in claim 2 , further comprising a mouthpiece secured directly on the mouthpiece securing means ( 11 ), wherein the sanitary valve ( 1 ) is adapted to be inserted in a valve-receiving space ( 20 ) of the fitting ( 2 ) and is adapted to be fixed on the fitting ( 2 ) by the mouthpiece secured on the mouthpiece securing means ( 11 ), or the sanitary valve ( 1 ) has a securing ring ( 38 ) by which the valve is adapted to be on the fitting ( 2 ).

4. The sanitary valve ( 1 ) as claimed in claim 2 , further comprising a jet regulator secured directly on the jet regulator securing means, and the sanitary valve ( 1 ) is adapted to be inserted in a valve-receiving space ( 20 ) of the fitting ( 2 ) and is adapted to be fixed on the fitting ( 2 ) by the jet regulator secured on the jet regulator securing means, or a mouthpiece that is secured directly on the mouthpiece securing means ( 11 ) has a jet regulator, or a jet regulator is arranged between the mouthpiece and the outflow opening ( 10 ).

5. The sanitary valve ( 1 ) as claimed in claim 4 , wherein the mouthpiece has an inner thread and the valve housing ( 3 ) at the outflow opening ( 10 ) has a corresponding outer thread ( 19 ), or the mouthpiece has an outer thread ( 19 ) and the valve housing ( 3 ) at the outflow opening ( 10 ) has a corresponding inner thread ( 32 ), or the jet regulator has an inner thread and the valve housing ( 3 ) at the outflow opening ( 10 ) has a corresponding outer thread ( 19 ), or the jet regulator has an outer thread ( 19 ) and the valve housing ( 3 ) at the outflow opening has a corresponding inner thread ( 32 ).

6. The sanitary valve ( 1 ) as claimed in claim 1 , further comprising at least one of a channel ( 21 ) configured to be closed toward the fitting ( 2 ) or a pressure chamber ( 28 ) configured to be closed toward the fitting ( 2 ) formed through the valve housing ( 3 ) and the adjustment device part ( 13 ), such that there is adapted to be no contact between the fitting ( 2 ) and a liquid flowing through the sanitary valve ( 1 ).

7. The sanitary valve ( 1 ) as claimed in claim 1 , wherein the clamping device ( 12 ) has two parts ( 22 ) which are connectable to each other and which, in an assembled position, form a hollow cylinder that encloses and firmly connects the valve housing ( 3 ) and the adjustment device part ( 13 ) at least in a coupling region ( 25 ).

8. The sanitary valve ( 1 ) as claimed in claim 7 , wherein the clamping device ( 12 ) permits a firm connection of the valve housing ( 3 ) and of the adjustment device part ( 13 ) outside the fitting ( 2 ).

9. The sanitary valve ( 1 ) as claimed in claim 1 , further comprising at least one fixing element ( 26 ) having a maximum external diameter that is configured such that the sanitary valve ( 1 ), in a state when inserted into the fitting ( 2 ), is fixed in a radial direction, with the at least one fixing element ( 26 ) being configured to bear on an inner wall ( 27 ) of a valve-receiving space ( 20 ), such that the sanitary valve ( 1 ) is adapted to be inserted into the fitting ( 2 ) or is adapted to be removable from the fitting ( 2 ) exclusively in an axial direction.

10. The sanitary valve ( 1 ) as claimed in claim 9 , wherein the at least one fixing element ( 26 ) is formed by at least one of the clamping device ( 12 ) by which the valve housing ( 3 ) and an adjustment device part ( 13 ) are connected to each other or by a bearing element ( 14 ) formed or mounted on the valve housing ( 3 ) and with which the valve housing ( 3 ) adapted to bear on a through-opening ( 16 ) in a wall ( 15 ) of the fitting ( 2 ).
