Abstract

The invention relates to a homogenizing valve which comprises two or more pressurized, movable valve cones, two or more valve seats, and a valve housing which surrounds the valve cones and the valve seats. The valve cones and the valve seats are arranged such that between them are formed constrictions, which constitute homogenization gaps having a gap height h. Between each individual valve cone and each individual valve seat are formed two homogenization gaps, of which one homogenization gap is radially arranged and one homogenization gap is axially arranged. The homogenizing valve is intended for use in existing homogenizers and is especially produced to be able to acquire an effective homogenization for liquids which are processed at a lower pressure and with a large flow, such as pasteurized milk, for example.
