Abstract
A valve for a milk pipeline which includes an elastic, tubular sealing unit mounted between two connectors in the milk pipeline, and a housing surrounding the sealing unit so as to define a closed chamber therebetween. The sealing unit can be brought by an external over-pressure in the chamber into a fully collapsed and closed position. Also, the valve is provided with a structure which engages at least one section of the sealing unit and applies a force directed substantially radially outwardly, so that the sealing unit is at least partly collapsed in its non-actuated state. As a result, the valve can be reliably closed with a small external over-pressure in the chamber.
