Abstract: A device and method for selectively closing and opening a flow path through a sealing element. The device includes second and third tubulars positioned within a bore of a first tubular. A sealing element having a bore is positioned between the second and third tubulars within the bore of the first tubular. The sealing element may be connected to one or both of the tubulars. Bores of the second and third tubulars communicate with the bore of the sealing element to provide a flow path. Movement of the third tubular with respect to the second tubular buckles the sealing element inward to selectively close a portion of the flow path. The third tubular may be moved away from the second tubular to reopen the flow path. The sealing element may engage a structure within the bore of the sealing element to selectively close the flow path through the sealing element.
