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.

In this book, the author shares his expertise gained over the last 35 years of applying and selecting control valves for a broad range of applications. The material presented is based on the content of control valve application, selection and training seminars he has presented to a variety of control valve users. Topics include: *How to properly size and select a control valve *Selecting the right valve flow characteristic to match the process *Control valve installed characteristics and installed gain *How analysis of installed gain can aid in proper control valve selection *Behavior of both gas flow and liquid flow in control valves, including noise reduction methods *Prediction and reduction of cavitation damage in liquid applications *Impact of the control valve on undesired process variability *Valve performance recommendations

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
