This volume is part of the Practical Guide Series developed and published by the ISA, the International Society for Measurement and Control. The Practical Guides were conceived because of a shortage of published material in the field of measurement and control that bridges the gap between theory and actual industrial practice. Many books in the field have catered to the needs of technical students, who need to be oriented to basic control theory and concepts, or college-level readers, who are interested in engineering mainly from a classroom perspective. There are handbooks for practicing engineers that cover measurement and control, but these handbooks often devote only a chapter or two to topics that merit more attention. Within the Practical Guides Series, separate volumes address each of the important topics and give them comprehensive, book-length treatments. Each book in the series can be understood and used by technical students, sales engineers, sales personnel, and managers, and relied upon by those who have "real-live" industrial concerns such as correct application, safety, installation, and maintenance. Another unique feature of the Practical Guides is the stress placed on the actual experience of measurement and control practitioners. The Practical Guides are overseen by various Volume Editors and a Series Technical Editor, who have extensive experience in measurement and control. The Volume Editors have been selected for their specific expertise in the volume topics, and bring together numerous Contributing Writers with even more specialized knowledge. The Series Technical Editor, who is responsible for general technical consistency within each volume and across all volumes, helps guide the Volume Editors. The Practical Guides capture the hard-earned experience of the writers and, by employing examples and recording anecdotal observations, make that experience as applicable for the reader as possible. Case studies, either hypothetical or based on real case histories, are used to illustrate typical situations and show how good planning and practical applications made the difference between success and failure. Some of this information has never been documented before. This volume is designed to be at home in a library, in a classroom, or on the plant floor. The comfortable reading style, large pages, and frequent illustrations will contribute to ease of use. The page design uses graphics to "call out" some of the major points of the text, such as crucial safety checks and important examples. Each Practical Guide gathers widely scattered information in a single text, with bibliographies directing the reader to other sources. |
TABLE OF CONTENTS Chapter 10.25 - Control Valve Features: About the Author
About the Author In memory of Alexandra Perandinou-Petersen (1944-1997). Born and initially raised on Paros, Cyclades Islands, Greece, Alexandra Perandinou-Petersen graduated from high school in Athens, then earned a bachelor's degree in mechanical engineering (1968) from Polytechnic University, Athens, Greece. Soon thereafter, she arrived in the U. S. for post-graduate studies at Stanford University. However, before her first semester ended, she received and accepted employment (to last over 18 years) with Bechtel Corporation in San Francisco beginning her professional career. Although continuing academic pursuits (additional undergraduate mechanical engineering at San Francisco State and graduate studies in chemical engineering at U. C. Berkeley), her main focus was to be an active engineer. She gained multi-faceted experience in the engineering design, installation, start-up and operational areas of mechanical, instrumentation and process and control/monitoring systems for fossil and nuclear power plants, water and wastewater utilities, petroleum refineries and defense waste processing facilities. Alex also was interested in teaching- developing and presenting classes and seminars on control systems and instrumentation for EPRI, ISA, and co-workers at Bechtel Corp. She developed test procedures and detailed design packages while an on-site systems engineer for PGE at their Trojan Nuclear Power Plant in Oregon and PG&E at their Diablo Canyon Nuclear Power Plant. Some of her published work included "Control Selection is the Key to Control Valve Operation" (Chemical Processing, August 1994) and "Guidelines for the Selection and Application of Power Plant Control Valves" (EPRI-TR-10251, March 1993). She was also an ISA senior member (PMCD, Power and Analytical Divisions). Special acknowledgment to Lawrence Pulley for his technical review of this chapter. Mr. Pulley is presently a consulting engineer with Pacific Gas & Electric Company. He has over 25 years experience in specifying, installing, and troubleshooting valves in the power and process industries. He is a graduate of the Merchant Marine Academy, and is a registered civil and mechanical engineer in California. |
