This course will equip attendees on the principles of the operation and maintenance of valves, pumps, and compressors one at a time. Valves, Pumps, and compressors applications are extensively useful in many process industries. Understanding how to operate the valves, pumps & Compressors correctly as well as knowing the appropriate maintenance and troubleshooting methods are vital for trouble-free plant operation. During the course participant’s discussion, comments, and bringing up their own problems are welcomed and encouraged. The training will be in three modules. Each module will treat one of the three instruments.
