1. A valve for a product-guiding processing plant, comprising a housing having a housing portion having a cylindrical inner wall, and having a longitudinal axis; a closure member arranged in the housing and being displaceable in direction of the longitudinal axis of the housing in a direction of closure between an open position and an closed position; a closure member seat arranged on the cylindrical inner wall of the housing portion; a sealing element arranged on the closure member that cooperates in a sealing manner with the closure member seat in the closed position of the closure member, and is distanced from the closure member seat in the open position of the closure member; a scraper arranged ahead of the sealing element, as viewed in direction of closure of the closure member from the open position into the closed position, the scraper being moved along and in contact with the cylindrical inner wall of the housing portion when the closure member is displaced from the open position into the closed position, for detaching product residues from the cylindrical inner wall of the housing portion; wherein the scraper is tiltable radially outwardly from a rest position in the open position of the closure member; wherein the scraper has a lip, which, in a longitudinal section parallel to the longitudinal axis, tapers radially outwardly to form an edge; wherein the lip is a first lip, and the scraper has a second lip, which is spaced from the first lip in direction of the longitudinal axis and is arranged ahead of the first lip, as viewed in the direction of closure of the closure member from the open position into the closed position; wherein the first lip tilts radially outwardly when the second lip contacts the cylindrical inner wall of the housing portion.
