Training Valves Operation and Maintenance


Course Description

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 along with the economics of the whole activity. Different application needs to select the appropriate valve type of a particular flow characteristic. Operation with 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 of the particular type of valves.
