Valve Actuators: A comprehensive introduction to the design, selection, sizing, and application of valve and damper actuators

This book is intended as a guide for automated valve end users, engineers and valve industry professionals that need to understand valve actuators. It describes the various types of electric and fluid powered actuators in terms of design, power supplies, controls and sizing.
The reader is taken through the logical steps of selecting the correct actuator for their application, including isolating, modulating and fail safe variations.
There are sections on matching actuators to new valves and also retrofitting actuators to existing valves.
Examples of where actuators are found in various industrial applications and a comprehensive technical appendix make this book a valuable reference manual.

PREVIEWS -

"An amazing job of explaining and illustrating actuators, and of course the engineering principles. We need engineering books like this: ones that explain engineering in a well written and digestible form".....Sir James Dyson

"This book covers the many and varied types of actuator designs. It helps users understand the type of actuator which is suitable for a particular valve and application. This is an easy to access reference work on all you will ever need to know about valve actuators."......... Bill Whiteley, Chairman Spirax Sarco Engineering Plc and former CEO Rotork Plc.

"This book should be on every engineer's bookshelf that works in the process or process control industry. It provides the link between the valve and the process. The reader is led through the process of application, selection, sizing, system design and specifying of the actuator."........ Edward Stillwell, PE Control System Engineer
