Servovalves are a key factor in determining the performance characteristics of an electrohydraulic position servo. This paper examines the interrelationships between servovalve parameters and system requirements. A brief description of the configuration and operation of a typical servovalve is presented. Key servovalve parameters are identified, defined, and discussed. System performance considerations are identified, and the interrelationships between system requirements and servovalve parameters are examined. Examples of servovalve parameters for missile, aircraft and industrial systems are given to illustrate the effect of system requirements on a servovalve. Finally, general guide-lines for selecting and specifying servovalve parameters are given.
