Sanitary valve

A sanitary valve (1, 201) comprising:

• a main valve (4, 204) which has a movable diaphragm (5, 205) is movable between a closed position, in which the diaphragm (5, 205) lies tightly against a valve seat (6, 206) of the main valve (4, 204), and at least one open position in which the diaphragm (5, 205) is spaced from the valve seat (6, 206);
• an inner housing (2, 204) having an interior in which the main valve (4, 204) is provided,
• an outer housing (3, 203) in which the inner housing (2, 202) is mounted so as to be rotatable about a rotational axis (L);
• the inner housing (2, 202) is equipped with a first valve opening (7, 207) which is fluid-conductively connected to a first valve opening (8, 208) in the outer housing (3, 203) in order to form a valve outlet of the sanitary valve (1, 201), which pair of said first valve openings (7, 8;
• 207, 208) is arranged on the rotational axis (L);
• the inner housing (2, 202) has at least one second valve opening (9, 209) which is arranged on an outside relative to the valve outlet and is paired with at least one second valve opening (10, 11;
• 210) in the outer housing (3, 203) in order to form at least one valve inlet (12, 13;
• 212) of the sanitary valve (1, 201);
• the respectively paired ones of the second valve openings (9, 10, 11;
• 209, 210) movable into congruence by a relative twisting of the inner housing and the outer housing (2, 3;
• 202, 203) such that a remaining clear opening cross-section of the at least one valve inlet (12, 13;
• 212) created by the congruence of the respectively paired ones of the second valve openings (9, 10, 11;
• 209, 210) is variable;
• the inner housing (2, 202) has a pot-shaped housing lower part (14, 214), with a pot-base inside from which a valve connector (15, 215) protrudes which connects the first valve opening (7, 207) of the inner housing (2, 202) forming the valve outlet to the valve seat (6, 206) which is formed by a free sleeve end region of the valve connector (15, 215);
• and
• the housing lower part (14, 214) having the valve openings (7, 9;
• 207, 209) of the inner housing (2, 202) thereby lies fluid-tightly on the outer housing (3, 203), at least in a ring zone of the pot base on an outside relative to the valve openings (7, 8, 9, 10, 11;
• 207, 208, 209, 210).
