Summary

The hydraulic servo valve is one of the most critical components in determining the performance of a hydraulic positioning, velocity or pressure control application. Highly dynamic and precise applications such as material testing, structural testing, simulation and plastics molding machinery have come to rely upon the accuract, dynamic performance, and reliability of the latest hydraulic servo valve.  It is in this context that we take an indepth look into some of most critical elements of an electrohydraulic servo valve.

The basic elements of the servo valve are the torque motor, flapper, spool, and feedback mechanism.  The feedback mechanism is considered a critical component in a servo valve due to its role and the vast number of mechanical cycles it is subjected to over its lifetime.  This mechanical component has undergone a tremendous amount of research and development to achieve life expectatncies that are well above 1 billion cycles, but this is only achievable with the right selection of materials, manufacturing techniques, and mechanical designs.

Our white paper intends to provide the design engineer with the basic anatomy of a servo valve and evolution of the design since first invented by William C. Moog.  Empirical test data demonstrating the value and the reasons for selection of materials, manufacturing techniques and mechanical solutions is also provided.  you will also learn the reasons why this product is now more rugged and high performance than others in the marketplace.
