Control Valve Sizing, Selection & Maintenance

 

Introduction:

It is claimed that the majority of control valves throughout the world have not been correctly sized and that large numbers operate on manual mode. Whether this is true or not is difficult to establish but we do know that the method of sizing and selecting a control valve for a specific application is generally not well understood. Although there are many factors that need to be taken into account the subject is not difficult to understand if dealt with in a logical manner. Many maintenance problems result from people treating the symptoms of a problem rather than tackling the true cause, a basic understanding of the principles is all that is usually needed to solve the problem for good. This course is designed to maximize knowledge retention and understanding. It provides an opportunity for participants to discuss, specific problems and appropriate solutions. It will enable you to understand what happens inside a control valve from basic fluid mechanics point of view.

Course Objectives:

 

By the end of this course delegates will be able to:

  • Appreciate the difference between cavitation and flashing, and know what choked flow is
  • Do simple calculations to determine CV values
  • Recognize severe service applications and have an appreciation for the methods of tackling the problems associated with such applications
  • Know about all the different types of control valves commonly in use and understand the relative advantages of each
  • Choose between different characteristics on offer and specify seat leakage rates
  • Size actuators for linear and rotary applications and know the relative advantages of pneumatic, hydraulic and electric types
  • Have a basic understanding on how to select materials for bodies, trims, packing boxes, and gaskets
  • Make use of a computer sizing program to assist with the selection of control valves
  • Understand the failure modes for control valves and demonstrate new approaches to troubleshooting
