Abstract
An homogenization valve design yields improved homogenization efficiency. The length of the valve surface relative to the valve seat or land is controlled so that the overlap is limited. This allows convergence between turbulent mixing layers and a homogenization zone. Preferably some overlap is provided, however, to contribute to the stability of the valves and avoid destructive chattering.
