Valves Operation and Designs

A complete understanding of construction details & functioning of valves for successful operation of your piping system

Valves Operation and Designs

  • Understand valves and control valves working principles for successful operation of your plant and piping systems
  • Understand valve construction details (bonnet, stem, disk, seat, packing, body, etc)
  • Know the characteristics and applications for each valve type (ball, plug, gate, pinch, butterfly, diaphragm, check, needle…)
  • Know how to choose the correct valve for a certain application
  • Know how to dismantle and assemble all types of valves using 3D and 2D models
  • Identify and know the principles of operation of common valve actuators (pneumatic, hydraulic, electrical, etc)
  • Understand how single acting and double acting pneumatic actuators work through graphics and 3D animations
  • Understand the principle of fail open (FO) and fail close (FC) actuators
  • Know how to convert a single acting spring return actuator to a double acting actuator and vice versa
  • Know how to convert a fail close actuator to a fail open actuator and vice versa
  • Learn how to size valves
  • Learn how to calculate the resistance coefficient “K” of any valves
  • Learn what the flow coefficient “Cv” of a control valve means and how to use it in assessing flows and pressure drops
  • Understand the theory of regulating flow with control valves
  • Understand the concepts of cavitation and choking in control valves through graphics and 3D animations
  • Learn how to size and select a control valve when designing and operating any piping system for both gases and liquids
  • Know and identify valve symbols on engineering drawings such as P&ID’s
  • Know the standards and conventions for valve status (open, closed, throttled)
  • Identify valve position and failure mode on your P&IDs (LO, LC, FO, FC, FAI…)
  • And much more…
Requirements
  • Some engineering or field knowledge is preferable but not mandatory. All the concepts are explained in depth using an easy to understand language to allow students to build their knowledge from the ground up
Valves Operation and Designs Description

Dear student,

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.

Valves Operation and Designs 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 modelscross-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 losspressure 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.

 

Valves Operation and Designs course is for:

  • Chemical, Process, Petroleum Engineers
  • Design Engineers
  • Piping Engineers
  • Plant Engineers
  • Facility Managers
  • Maintenance Technicians
  • Mechanics
  • Plant Operators
