ISA Publishes New Edition of Control Valve Primer

Baumann, a holder of more than 150 patents, and author of over a hundred publications in control valve technology, shares his expertise on designing control loops and selecting final control elements.

The fourth edition of Control Valve Primer has been updated and significantly enlarged by adding sections on digital positioners, increased coverage of distributed control systems (DCSs) and smart positioners, a new hydrodynamic and cavitation noise estimate, updated standards to reflect latest IEC versions and a new chapter on seat leakage and seat material.

Baumann says this book is intended primarily for novice instrument engineers who, even though they've been crammed full of feedback theory in college and consider themselves experts in computer programming, are suddenly faced with designing a process plant control loop. The easy-to-read text provides shortcuts through complex sizing and noise calculation formulas including for liquids and cavitation, and gives practical advice on how to apply control valves for safety, reduced energy costs, loop stability, and easy maintenance.
