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
Control valves are imperative elements in any system where fluid flow must be monitored and manipulated. A complete control valve is made of the valve itself, an actuator, and, if necessary, a valve control device. The actuator is what provides the required force to cause the closing part of the valve to move and the valve control devices keep the valves in the proper operating conditions; they can ensure appropriate position, interpret signals, and manipulate responses.Selection of the proper valve involves a thorough knowledge of the process for which it will be used. When implementing a control valve into a process, one must consider not only the appropriate type of valve and its material of construction, but also the correct sizing to ensure it performs its designated task without any adverse occurrences in the system.This 4-hour quick book provides an overview of control valve with emphasis on the sizing and selection. This course is for mechanical, instrumentation and process engineers involved in sizing, selecting and applying process control valves. No specific prerequisite training or experience is required.Learning ObjectiveAt the conclusion of this course, the reader will:• Differentiate between various types of valves and the benefits of each;• Understand the operation of control valve in a control loop;• Understand how to evaluate and apply actuators and positioners for specific applications;• Understand the basic hydraulics and the relationship between the Cv, flow rate and pressure drop;• Understand how to size valves for any flow condition likely to be found in a process plant;• Understand how to select the proper valve characteristic for a given process;• Understand how the installed characteristics can match closely to the inherent characteristics;• Understand the methods to address system performance issues such as cavitation, flashing and chocked conditions;• Understand the factors influencing the selection of control valves.
