Original Abstract Submitted
a butterfly valve assembly includes a butterfly valve housing defining a channel for accommodating a flow of gas therethrough. the assembly includes a butterfly valve adjustable in the housing between a closed position preventing the flow of gas through the channel and an open position opening up the channel for allowing passage of the flow of gas. a pivot shaft is rotatable about a pivot shaft axis and has first and second pivot shaft end portions corresponding to first and second bearing regions. a disk-shaped butterfly valve element is supported on the pivot shaft. at least one of the first and second bearing regions includes a bearing unit rotatably supporting the pivot shaft. the pivot shaft has an outer peripheral surface. at least one seal is subject to an axial load by the bearing unit and lies against the outer peripheral surface of the pivot shaft.
