Abstract

A ball valve has a valve housing (2) receiving ball spindle (6) pivoted around an axis in the housing (2). A ball body (12) as a blocking element is between the input part and the output part of a media passage (4) of the housing. The flow opening (14) located in the ball body (12) is alignable with the passage (4) for unblocking the ball valve by turning the ball spindle (12). The ball body (12) is supported on two identical end sections (8, 10) connected to and axially spaced from the ball body (12). The support on at least one end section (8, 10) is a support cover (26) having integrated slide bearing elements (34, 36) detachably mounted on the housing (2).
