Overview

Description

Piping systems, power plants and industries are fitted with valves for controlling purposes and safety requirements. Understanding the function of each valve type will have a significant reflection on the process quality, equipment and plant reliability. Technical staff should have sound knowledge on the problems associated with valves for proper diagnosis, troubleshooting and maintenance of the particular type of valve.
This course is designed to help students to understand selection, classification, application and maintenance of control valves and actuators.
After completing this course, students will have expert knowledge and skills to independently evaluate possible valve operation, selection and design solutions.
