Book 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.

Book Description
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

Book Description
Presents equations for predicting the flow of compressible and incompressible fluids through control valves. The equations for compressible fluids are for use with gas or vapor and are not intended for use with multiphase streams such as gas-liquid, vapor-liquid or gas-solid mixtures. The equations for incompressible flow are based on standard hydrodynamic equations for Newtonian incompressible fluids and are not intended for use when non-Newtonian fluids, fluid mixtures, slurries, or liquid-solid conveyance systems are encountered.

Book Description
The latest update to Bela Liptak's acclaimed "bible" of instrument engineering is now available. Retaining the format that made the previous editions bestsellers in their own right, the fourth edition of Process Control and Optimization continues the tradition of providing quick and easy access to highly practical information. The authors are practicing engineers, not theoretical people from academia, and their from-the-trenches advice has been repeatedly tested in real-life applications. Expanded coverage includes descriptions of overseas manufacturer's products and concepts, model-based optimization in control theory, new major inventions and innovations in control valves, and a full chapter devoted to safety. With more than 2000 graphs, figures, and tables, this all-inclusive encyclopedic volume replaces an entire library with one authoritative reference. The fourth edition brings the content of the previous editions completely up to date, incorporates the developments of the last decade, and broadens the horizons of the work from an American to a global perspective. Béla G. Lipták speaks on Post-Oil Energy Technology on the AT&T Tech Channel.
