AbstractA fluid operated pinch valve comprises a flexible sleeve fixed at its ends within a valve casing that has a laterally facing opening through which the sleeve may be inserted and replaced without removing the valve casing from the flow line. A casing cover section has a planar sealing face that bridges the opening for sealing engagement with the main casing section, and which also seals against linear sealing flanges on ends of the flexible sleeve.
