The paper presents a comparison of the accuracy of the positioning servo hydraulic proportional valves belonging to different classes (with improved dynamic performance and the typical proportional valve) in the case of selected kinematic parameters and external load conditions. In the tested hydraulic servo drive, the Compax3F controller by Parker Hannifin was used. The authors described also the procedure of analytical selection of the adjustments for the proportional regulators and the applicability of specificied types of servo hydraulic proportional valves in applications requiring of various positioning accuracy. As the quality factors of the analyzed parameters the maximum control deviation values and Peak to Peak control deviation values have been used.
