Abstract
It has been determined that homogenizing efficiency can be increased substantially by expressing the fluid through a valve in which the valve seat has a knife edge configuration and the valve gap has an optimum height of less than 0.003 inch. To provide the high flow rate required in most industrial applications, the total length of slits within a valve assembly, each having the optimum gap, is selected for given homogenizing and back pressures. In a preferred embodiment, in order to provide the extended slit length necessary within such a valve assembly, a plurality of annular valve slits are provided between stacked valve members within the assembly.
