...Dynamic Performance and Precision

The hydraulic servo valve is where the dynamic performance and precision positioning capabilities in a hydraulic motion control system are realized.  As such the electrical design, mechanical design, material selection, and manufacturing process are all critical for ensuring the performance specifications of the servo valve are maintained over the expected lifetime.  The servo valve is part of a closed-loop control system comprised of electromechanical mechanisms, and embedded software algorithms.  It is incumbent upon the design engineer to fully understand the primary elements of this closed-loop system that impact the dynamic performance and life expectancy of a servo valve so he or she can make the best selection for the machine or application.
