Valve Selection Guide
Control valves are an increasingly vital component of modern manufacturing around
the world. 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 fourth 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.
Chapter 5 is a comprehensive guide to selecting the best control valve for
an application.
Chapter 6 covers the selection and use of special control valves.
Chapter 7 covers desuperheaters, steam conditioning valves, and turbine
bypass systems.
Chapter 8 offers typical control valve installation and maintenance procedures.
Chapter 9 includes information on control valve standards and approval
agencies throughout the world.
Chapter 10 offers useful tables of engineering reference data.
Chapter 11 includes piping reference data.
Chapter 12 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 and the Crane Company.
Valves are the components in a fluid flow or pressure system that regulate
either the flow or the pressure of the fluid. This duty may involve
stopping and starting flow, controlling flow rate, diverting flow, preventing
back flow, controlling pressure, or relieving pressure.
These duties are performed by adjusting the position of the closure
member in the valve. This may be done either manually or automatically.
Manual operation also includes the operation of the valve by means of a
manually controlled power operator. The valves discussed here are manually
operated valves for stopping and starting flow, controlling flow
rate, and diverting flow; and automatically operated valves for preventing
back flow and relieving pressure. The manually operated valves are
referred to as manual valves, while valves for the prevention of back
flow and the relief of pressure are referred to as check valves and pressure
relief valves, respectively.
Rupture discs are non-reclosing pressure-relieving devices which fulfill
a duty similar to pressure relief valves.
