  • Aseptic constant-flow valve
    Patent number: 4776367
    Abstract: Aseptic constant flow valves to be used, for example, in the dairy industry should be readily washable and allow sterilization by means of conventional washing and sterilizing agents. A valve which fulfils these requirements comprises an operating chamber with inlet and outlet which is connected to the valve housing and therefore can be circulation-washed and sterilized together with the latter.
