Gas Flow and Aerodynamic Noise in Control Valves

This one hour webinar discusses the nature of the flow of gas through control valves including choked flow and how experimentally determined valve parameters are incorporated in the valve sizing  calculations. A short discussion of basic acoustics is presented to provide an understanding of noise terminology. Aerodynamic noise generation is discussed along with descriptions of various valve designs that reduce the potential for excessive noise. Each participant will receive a certificate of completion in the mail.

Who should attend?

Technicians and engineers who want to know how to properly apply control vales in gas service or those who need to solve
problems that are caused by improperly selected control valves.


  • Gas terminology
  • Choked flow
  • Terminal pressure drop ratio
  • Cause of aerodynamic noise
  • Aerodynamic noise reduction techniques
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.
