Industries that use pumps, seals and pipes will also use valves and actuators in their systems. This key reference provides anyone who designs, uses, specifies or maintains valves and valve systems with all of the critical design, specification, performance and operational information they need for the job in hand. Brian Nesbitt is a well-known consultant with a considerable publishing record. A lifetime of experience backs up the huge amount of practical detail in this volume.* Valves and actuators are widely used across industry and this dedicated reference provides all the information plant designers, specifiers or those involved with maintenance require* Practical approach backed up with technical detail and engineering know-how makes this the ideal single volume reference* Compares and contracts valve and actuator types to ensure the right equipment is chosen for the right application and properly maintained

This new 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

Valves are the components in a fluid flow or pressure system that regulate either the flow or the pressure of the fluid. They are used extensively in the process industries, especially petrochemical. Though there are only four basic types of valves, there is an enormous number of different kinds of valves within each category, each one used for a specific purpose. No other book on the market analyzes the use, construction, and selection of valves in such a comprehensive manner. - Covers new environmentally-conscious equipment and practices, the most important hot-button issue in the petrochemical industry today - Details new generations of valves for offshore projects, the oil industry's fastest-growing segment - Includes numerous new products that have never before been written about in the mainstream literature

This revised and updated 3rd edition outlines the structure of the global industry and future trends, highlights issues facing the industrial valve industry, assesses market and technological trends, offers market figures and forecasts to 2009 and identifies the major players. The report also provides a detailed overview of merger and acquisition activity in the industrial valve industry since 2000.

The first book to combine all of the various topics relevant to low-cost automation. Practical approach covers methods immediately applicable to industrial problems, showing how to select the most appropriate control method for a given application, then design the necessary circuit. Focuses on the control circuits and devices (electronic, electro-mechanical, or pneumatic) used in small- to mid-size systems. Stress is on on-off (binary) control as opposed to continuous feedback (analog) control. Discusses well-known procedures and their modifications, and a number of original techniques and circuit design methods. Covers ``flexible automation,'' including the use of microcomputers.
