Abstract: A pinch valve having a valve housing, wherein the valve housing has a valve inlet and a valve outlet and a sleeve arranged between the valve inlet and the valve outlet, wherein the sleeve is connected to the valve inlet and the valve outlet and forms a valve channel, which valve channel can be flowed through in a conveyed direction by a conveyed medium, wherein the pinch valve further has a pinch bar, which moves back and forth in a closing direction between an open position and a closed position, wherein the pinch bar is in contact with the sleeve at least in the closed position, such that the pinch bar exerts a closing force on the sleeve in the closing direction, such that a channel cross-section of the valve channel perpendicular to the conveyed direction between the valve inlet and the valve outlet can be reduced and/or closed, wherein the sleeve has at least two material layers between which a first textile fabric, preferably a mesh, is arranged.

Abstract: The present invention relates to a pinch valve (1) with a housing which has an inlet (2), an outlet (3) and a control opening (4) for connection to a pressure medium, inlet and outlet being connected to each other via a passage, the passage having at least two sections with a different cross-section (12), and a valve sleeve (16) which is connected to the inlet and outlet and arranged such that it forms a valve channel between inlet and outlet, the valve sleeve (16) moving, upon application of a pressure medium to the control opening (4), such that the channel cross-section between inlet and outlet is reduced or closed. In order to provide a pinch valve can be produced simply and at favourable cost and also seals reliably, it is proposed according to the invention that the housing is formed in at least two parts, one housing part forming the section with a smaller passage cross-section and the other housing part forming the section with a larger passage cross-section.
