3 Properly selected and maintained CONTROL valves increase efficiency, safety, profitability, and ecology. The CONTROL VALVE HANDBOOK has been a primary reference since its first printing in 1965. This fifth edition presents vital information on CONTROL VALVE performance and the latest technologies. Chapter 1 offers an introduction to CONTROL valves , including definitions for common CONTROL VALVE and instrumentation terminology. Chapter 2 develops the vital topic of CONTROL VALVE performance. Chapter 3 covers VALVE and actuator types. Chapter 4 describes digital VALVE controllers, analog positioners, boosters, and other CONTROL VALVE accessories.
4 Chapter 5 is a comprehensive guide to selecting the best CONTROL VALVE for an application. Chapter 6 addresses the selection and use of special CONTROL valves . Chapter 7 explains desuperheaters, steam conditioning valves , and turbine bypass systems. Chapter 8 details typical CONTROL VALVE installation and maintenance procedures. Chapter 9 contains information on CONTROL VALVE standards and approval agencies across the world. Chapter 10 identifies isolation valves and actuators. Chapter 11 covers discrete automation. Chapter 12 discusses various process safety instrumented systems.
5 Chapter 13 provides useful tables of engineering reference data. Chapter 14 includes piping reference data. Chapter 15 is a handy resource for common conversions. The CONTROL VALVE HANDBOOK is both a textbook and a reference on the strongest link in the CONTROL loop: the CONTROL VALVE and its accessories. This book includes extensive and proven knowledge from leading experts in the process CONTROL field, including contributions from the ISA.
