Abstract
This paper describes experimental and Computational Fluid Dynamics (CFD) analyses of the flow and flow force characteristics in hydraulic seat valves. The flow force compensation method were investigated based on balancing the axial fluid momentum by designing a rim on the rear edge of the poppet. There are many results of steady state characteristics of these valve designs, but mostly based on analyses of the flow force behaviour in order to optimise the performance of a certain design in a specific operating range. Here the aim is to establish a correlation between the overall flow field and the internal valve geometry in order to have a more general design tool. The results are some general design rules for flow and flow force coefficients expressed as functions of Reynolds number and valve geometry.
