Effect of Control Valve Sizing and Flow Characteristic on Controllability

This one hour webinar discusses the difference between a control valve’s inherent and installed flow characteristic, and defines the two most commonly found inherent flow characteristics. Rules of thumb are presented for selecting the correct inherent flow characteristic for a particular application and selecting the correct size control valve, along with technical justification for these rules of thumb. Each participant will receive a certificate of completion in the mail.

Who should attend?

Technicians and engineers who want to gain insight into selecting control valves that will do the best possible job of controlling a process, or who want to be able to recognize when poor control is being caused by an improperly selected
control valve.


  • Inherent and installed flow characteristics defined
  • Rules of thumb used for selection of valve size and inherent flow characteristic
  • Technical justification for the use of these rules of thumb
  • Effect of proper control valve sizing on controllability
  • Importance of selecting the proper inherent flow characteristic for good controllability

The speaker, Dr. Jon F. Monsen, PE, is a Control Valve Technology Specialist at Valin Corporation where he specializes in training, control valve applications, and smart digital products. Prior to joining Valin, he was a technology specialist at Metso Automation (parent company of Neles and Jamesbury) for 25 years. He has lectured extensively on the subject of control valve application and authored the chapter on “Computerized Valve Sizing” for the ISA Practical Guides Series book on
Control Valves.
