Valves & Control Valves : Principles, Operation & Design

Valves of various designs and applications are encountered nowadays throughout petroleum refining, petrochemical and process industries as well as in power generation and environmental engineering.

This course is designed to provide you with a complete understanding of construction details and functioning of valves. This understanding is a prerequisite for successful operation of your plant and piping system.

The course includes extensive graphics, 3D animations and cross-sectional views to give you a virtual practical exposure on valves.

In this course, you will :

1. Discover the major types of valves used in the process industry

2. Learn their components, their function & their operation

3. Have the opportunity to dismantle many valves and assemble them using 3D models, cross-sectional views and 3D animations

4. Also included in this course, an in-depth discussion on actuators and control valves. You will learn how control valves are used to regulate the flow of a fluid. Concepts such as head loss, pressure drop, valve coefficient “Cv”, flow resistance, valve curves and cavitation will be presented.

5. Finally, the course introduces you to valve symbols and representation in engineering drawings such as Piping & Instrumentation Diagrams (P&ID’s). Standards and conventions that apply to valves and their accessories will be discussed in details. You will learn how valve status and failure modes are depicted in engineering drawings.

So with no further ado, check out the free preview videos and the curriculum and we look forward to seeing you in the first section.

Also remember, as enrolled student you will have unlimited access to this material and one-on-one instructor support. So feel free to ask us for help in the Q&A section when needed. It will be our pleasure to help you and make sure you are learning valuable information with us.

Hope to see you there
