Beschreibung
Zusammenfassung:	A ball valve, in particular for explosion isolation in process pipelines, includes a housing pipe coaxial with the through-flow direction, bearing rings which are flanged respectively onto the end faces of the housing pipe and have bearing shoulders that engage in the internal opening of the housing pipe, a valve body, in the basic form of a ball ring having a continuous through-flow opening, mounted between the bearing shoulders via sealing rings inserted therein so as to be driven in rotation about an axis of rotation, extending perpendicularly to the through-flow direction, between a respectively stopped closed and open position, a rotary drive for the valve body, and stop recesses which are formed directly in the valve body and form end stops for stop protrusions on the housing pipe in order to define the closed and open position of the valve body.
