- 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.
- 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.).
