Hydraulics and Pneumatics

advertisement

 Almost all industrial operations need the movement, manipulation, or application of force to things. This is typically performed through the use of electrical equipment (such as motors or solenoids) or devices powered by air (pneumatics) or liquids (hydraulics).

A process control engineer wrote this book as a guide to the operation of hydraulic and pneumatic systems for all engineers and technicians who want to understand the components and operation of such a system. This second version has been completely revised to include all new advancements, such as the increased usage of proportional valves, and includes an additional expanded section on industrial safety.
