Servo Valve Characteristic Curves

, 2018
Typically, a servo valve is characterized by a series of curves which provide behavioural information of the servo valve under varying operating conditions. These curves are typically used in identifying the valve centre type, null bias, response to inputs of varying amplitudes at varying frequency and phase difference between system input and output ...

Comparative Analysis of a Hydraulic Servo-Valve

International Journal of Fluid Power, 2013
AbstractThe aim of this work was to obtain the correct hydraulic proprieties of a hydraulic spool servo-valve using computational fluid-dynamics (CFD) techniques and adopting an accurate enough mesh to analyse the flow pattern inside the valve. The zones where thickening of the mesh is necessary have been detected and a method to generate the mesh ...
