ABSTRACT:
A mixer valve has a valve cartridge arranged in interchangeable manner in a valve casing. A fixed control disk and a movable control disk can be moved counter to one another by an operating element in said valve cartridge. The latter has a roughly tubular casing, which is closed on the outside by a cup-shaped sleeve and on the inside by a cartridge bottom. As a result of this construction, the cartridge can be replaced particularly easily.
