The 7077 control valve for endless tubes offers a modern alternative to conventional pinch or diaphragm valves. The pinch valve can be used at any position on an endless tube for on/off and control operations. With no dead space, the highest hygienic demands can be met. For those applications where flexibility is not a priority, the 7070 pinch control valve offers an alternative and is integrated permanently in pipelines. Here also, the entire design can be used without any problems in food-related and sterile processes. Sterile valves can also be operated as control valves by fitting a positioner.
