overview
Power Plant and other petrochemical industries do deal with different types of valves. All piping systems are fitted with valves for controlling purposes or safety requirements. Understanding the function of each valve type will have an important reflection on the process quality, equipment and plant reliability, and the economics of the whole activity. Different application needs to select the appropriate valve type of a particular flow characteristics. Operation of the valve also affects the system and the process. Understanding the problems associated with valves is essential for diagnosis and troubleshooting and the needed maintenance for the particular type of valves.
The seminar will highlight:
- The understanding of the function of different types of valves
- The appreciation of the characteristics of valves
- The selection and sizing process
- The problems and phenomenon associated with valves operation
- The ability to carry out troubleshooting of valves
