A new book has recently been released by Chris Warnett called Valve Actuators. An up-to-date and comprehensive introduction to today’s valve and damper actuators, this new book is intended as a guide for automated valve end users, engineers and valve industry professionals that need to understand valve actuators.
The book 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.
