Electrohydraulic Servo Valves - Second Edition
Electrohydraulic servo valves are among the most precise and sophisticated control components in modern hydraulic systems. They form the backbone of high-performance motion control applications across aerospace, defense, steel manufacturing, marine equipment, and advanced industrial automation.

The second edition of the book offers a comprehensive yet practical look at electrohydraulic servo valves, covering how they work, their structure, and their static and dynamic characteristics. It also includes mathematical models, control concepts, and guidance on evaluating performance, troubleshooting, and maintaining these systems. Starting with basic fluid power and control concepts, the book gradually introduces torque motors, flapper-nozzle systems, jet-pipe amplifiers, spool dynamics, feedback systems, and closed-loop servo control.

A special focus is placed on dynamic behavior, including transfer functions, frequency response, stability, resonance, bandwidth, transient behavior, and PID control. The book also discusses common issues such as contamination, wear, noise, temperature effects, null shift, hysteresis, saturation, and leakage, explaining their causes, effects on the system, and ways to prevent them.

With helpful engineering drawings, real-world examples, and practical insights, this book makes the connection between theory and real-world application clear. It is a valuable resource for hydraulic engineers, maintenance teams, teachers, students, and anyone interested in understanding high-performance electrohydraulic control systems.
