Why Attend This Training Course?

Power Plant and other 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. Understanding the problems associated with valves is essential for diagnosis and troubleshooting and the needed maintenance for the particular type of valves. The purpose of this course will be to develop in participants a working knowledge of various valves, as well as the different procedures and regulations associated with their maintenance and installation. With the completion of this course the participants will be equipped with the basic knowledge required to identify valves, their construction, and repair of valves and their associated components. This course will also provide the attendee with the knowledge necessary to understand and enhance their mechanical aptitude in the area of valve maintenance and repair.

What Is The Training Course Methodology?

This training methodology illustrates the concepts involved in the above areas through practical consideration of actual real-life problems, as well as explanation of concepts by experts in area using video projectors and computer aided case studies based on practical applications. Participants will solve their system problem, where the trainee’s try to apply the skills learnt with guidance from our specialized experts. ACAD will provide participants a comprehensive assessment on the problems solved using the skills acquired in the training course.
