Beschreibung
Zusammenfassung:	The portions of the valve liner in a butterfly valve, against which the end thrust surfaces around the valve disc shafting bear, are inclined relative to a plane normal to the axis of the shaft so as to produce varying compressive resistance force so that the sealing action of these liner portions is greatest when the valve disc is in closed position.
