Abstract
The drain valve (1) has a valve tube (26) as well as an insert (37) with a float (38) in a valve housing (36). The float (38) is connected with the valve tube (26). In the bottom (49) of the insert (37) openings (39, 41a) are provided, which can be made to index by rotating a punched disk (40). For setting or resetting the flush water quantity, the punched disk (40) can be rotated by raising and turning the valve tube (26). Cogs (43) of the punched disk (40) will then engage in corresponding cutouts (45) at the lower end of the valve tube (26).
