The overall purpose of this course is to provide engineers and senior technicians in their relevant fields with the applied knowledge that enables them to efficiently select, maintain or repair different types of valves, including control valves and their accessories. The course provides a comprehensive overview about the basis behind the selection of different types of valves used in oil & gas industry. In addition it covers valves selection, installation, testing & carry out preventive, predictive and corrective maintenance on valves. Emphasis is placed on selection, sizing and maintenance of different valve types
Upon successful completion of this course, the delegates will be able to:
- The ability to carry out the selection and sizing process
- Understanding the problems and phenomenon associated with valves operation
- The ability to select the right valve for the particular application
- The ability to perform the necessary calculation for valve sizing
- The ability to carry out troubleshooting of valves and systems that valves are connected to
- The ability to perform troubleshooting of systems involving valves
- The ability to decide on the right maintenance plan concerning different types of valves
- Safety and relief valves play a vital rule for the safety concerning equipment and personnel
