Introduction

Training course introducion / brief

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.

The aim of this course is to provide delegates with a detailed overview of the operating performance of valves commonly employed in power plants and the manner in which they are chosen to provide the optimum configuration. This course will concentrate on the fundamental aspects, troubleshooting and diagnoses of valves and will address the operating problems which are often experienced by plant personnel. The pressure classes, codes and standards will be covered in the course. The course will cover valve installation, testing, maintenance and troubleshooting. Delegates will be able to acquire the practical knowledge to enable them not only to choose the correct valve for a particular application but also to be in position to resolve the common operating problems associated with this topic.

Main usage of valves in power plants
An understanding of different parameters affecting the operation of valves.
The ability to select the right valve for the particular application.
An understanding of the problems associated with valves like flashing, slamming and water hammer.
The ability to perform troubleshooting of systems involving valves.
Diagnose and repair valve failures.
Describe the proper procedures for valve disassembly, cleaning, and inspection.
Testing and inspection of valves according to international standards.
