A valve, especially a switch-over valve for large channel cross sections, is provided. A wing is pivotably mounted in a housing having channel connections. A fixating lever assembly provides for movement of the wing and includes a fixating lever and at least one link rod, one end of which is pivotably connected with the fixating lever while the other end is pivotably connected with the wing. A respective driver passes through and is mounted on opposite side walls of the housing. An inner end of each driver is connected to the fixating lever of a given one of the assemblies. A rotary drive mechanism engages an outer end of each driver.
