Abstract

A ball valve with a casing (1) that has at least two dome nut fittings (2, 3) and supports a sphere (11) that has two indentations (12, 13) and turns around a shaft (14). This is equipped with a handle (18;17,28) consisting of two sections and is held in a dome nut (6) of the casing. The main body (17) of the handle (18), turned towards the dome nut (6) of the handle, with one section (21) made in the shape of a well, must be attached to the shaft (14), protected against the relevant rotation but nevertheless sliding axially when reaching a stop (23). In this stationary section (21) a locking edge (33, 35, 36) is machined that corresponds to that of the dome nut (6) of the handle. The section of the handle opposite the dome nut of the handle encloses the main body (17) in the shape of a hood (28) and by so doing covers the handle (18) fastener on the shaft (14), for example a flat head screw (19).
