PUB – Geometry of Ball Seat Valves


A paper on “Geometry of Ball Seat Valves” was published at the International Journal of Fluid Power.


The macroscopic geometry of ball seat valves is important for the quality of the seal. This works discusses the influence of different geometric properties on the contact area, the contact pressure and their relation to the leakage. The leakage is calculated using the results of finite element method (FEM) calculations and Persson’s percolation based method. The following properties of the seat are examined: the angle, the curvature and the eccentricity.
