About Fluid Mechanics Of Control Valves: How Valves
Product Description This up-to-date work on final control elements presents theoretical and practical information in an easy, conversational style, which makes it an excellent reference for experienced instrument and process engineers as well as students who are new to the field. The book begins with a basic explanation of the function and purpose of control valves, explaining the various types of valves that are available along with their features and limitations. It also provides: • Directions for selecting the best valve for a given service and the right flow characteristics • Simplified equations for sizing control valves for liquids and gases under normal and special conditions, such as flashing and laminar flow • Directions for minimizing environmental problems, such as noise produced by turbulent or cavitating fluids and aerodynamic noise • Solutions to dynamic instability problems • Methods for improving control loop stability • Discussion on related safety issues such as "fail-safe" action and cybersecurity Many reference tables provide information that will be invaluable in valve selection, such as valve materials, temperature ratings, and valve dimensions. Also, for the benefit of international readers, examples and equations are presented in metric as well as U.S. customary terms and measurements. Review I am very impressed how easily I could understand what the writer was communicating. The book is very well organized, the font and white space balance comfortable to read, and the examples clear and supportive of the text so that even one only peripherally knowledgeable in the field can grasp its meaning. - M. Cating A valuable addition to the ISA library, and a good reference for valve users at all levels. Nowadays, too many people think of a control valve as a "commodity," but your book reminds us that there is a lot more involved to get the best results. - Stephen Boyle, chair of ISA SP75-07 I hope this book will become a reference at every university that teaches process control. Baumann's treatment of sound and noise is (to my knowledge) without precedent and similarly excellent is his discussion of efficiency and thermodynamics. I do hope that Baumann's advice on cybersecurity will be followed, before it is too late (our every nuclear power plant is a potential bomb). - Béla Lipták
