Description
Nearly all industrial processes require objects to be moved, manipulated or subjected to some sort of force. This is frequently accomplished by means of electrical equipment (such as motors or solenoids), or via devices driven by air (pneumatics) or liquids (hydraulics).
This book has been written by a process control engineer as a guide to the operation of hydraulic and pneumatic systems for all engineers and technicians who wish to have an insight into the components and operation of such a system.
This second edition has been fully updated to include all recent developments such as the increasing use of proportional valves and includes an extra expanded section on industrial safety. It will prove indispensable to all those wishing to learn about hydraulics and pneumatics.

About the Author
Andrew Parr is an Industrial Control Engineer, recently retired from ASW Sheerness Steel, Sheerness, the United Kingdom who worked in the steel industry for over thirty years. In 1980 he began specializing in sequence and closed-loop control systems using Programmable Controllers (PLCs) with hydraulic and pneumatic actuators. He has written fifteen books on electronics and process control including Logic Designers Handbook, Industrial Control Handbook, Programmable Controllers, Control Engineering, along with many amateur- level books, among them Introduction to Operational Amplifiers. His books have been widely translated into many languages, including Japanese, Polish, and Swedish. He and has presented papers at various international conferences, including ones on “Automation Systems in the Steel Industry” and on “Automated Fault Diagnostics”.
