  • Upon completion of the course, participants will be able to:
  • Recognize and understand how a valve works
  • Appreciate the different types of valves available
  • Apply valve sizing techniques, using software and other methods of calculation
  • Appraise the advantages and disadvantages of various types of positioners
  • Experiment with correctly tuning a control valve .
  • Have an understanding of the different types of pumps .
  • Be able to operate pumps as close as possible to the design efficiency.
  • Will be able to monitor pump efficiency, availability and reliability.
  • Be able to troubleshoot pump problems.

The Delegates

  • This course would primarily be aimed at people within the Instrumentation, Electrical, Mechanical, Process disciplines, who are actively involved in the utilization of valves (control or shut-off) and actuators, as well as those people who have the additional responsibility of sizing the valves, and making a decision on the composition and make-up of the valve.
  • It would also be of great value to those individuals who either have a keen interest in the field, or who have to manage the people working on the various valves , actuators and pumps . (In this respect, one could think in terms of Process Control Engineers, Electrical Engineers, Mechanical Engineers, Industrial Engineers, Designers and the like.).
