Pinch valve and a process for the production of a pinch valve

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.
