A number of different instructional methods are used throughout the course to allow interactive learning and to give practical examples from manufacturing and service industry to enable the delegates to operate, select and troubleshoot control and safety valves upon course completion.

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

• The ability to carry out the selection and sizing process
• Understand 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
