Sizing Valves for the Process Industry

A complete understanding of the valve sizing procedure for any flow conditions likely to be found in a process plant (ISA / API Standards)

What You Will Learn in This Course

  • Step-by-step valve sizing methodology 
  • Procedure of valve sizing in accordance with the ANSI & ISA recommendations
  • Sizing for liquids (incompressible fluids)
  • Sizing for vapors and gases (compressible fluids)

What is Covered in This Course

Designed around a series of practical examples which we work through to a solution, this valuable online course is an essential guide to understanding the valve sizing procedure. This understanding is a prerequisite for the successful operation of your plant and piping system.

In this course, we will present a step-by-step sizing methodology. We will show you how to proceed in the sizing of a valve in daily practice, how to determine the flow coefficient (Cv) when selecting a control valve size, how to predict the maximum flow rate that a selected valve will pass or how to determine the pressure differential that a selected valve will exhibit, just to name a few...

You will learn from our industrial experience what we wrongly calculated during project startup, debottlenecking, and commissioning. This should undoubtedly help you minimize the mistakes in the sizing and selection of your valves.

Included in this course is access to a valuable Valve Sizing Excel Spreadsheet. This tool will help you perform all the calculations we will discuss further in the course. It has all the sizing equations, numerical constants, and other parameters built right in.

The Valve Sizing Excel Spreadsheet provides well-organized technical data in the form of spreadsheet calculations indispensable for anyone involved in the sizing of valves. It presents formulae and data for:

    • Valve flow coefficients Cv
    • Flow of fluids through valves
    • Pressure drop through valves and attached fittings
    • Valve Reynolds Number calculations
    • Predicting maximum flow through valves in choked conditions
    • Representative values of valve capacity factors
    • And much more...

The spreadsheet includes two worksheets:

    1. Sizing for liquids (incompressible fluids)
        1. Non vaporizing flow conditions
        2. Choked flow conditions
    2. Sizing for vapors and gases (compressible fluids)

So as you can see here, detailed technical descriptions and basic step-by-step instructions will be provided to you along with practice sessions, a valuable Valve Sizing Spreadsheet, and numerous downloadable resources to emphasize the key learning points.


    • We assume that Microsoft Excel is installed on your computer and that you have basic knowledge of using Excel.
    • This Valve Sizing Excel Spreadsheet includes Visual Basic for Application function subroutines (VBA). Macros must be enabled for them to work.

Brilliant, highly informative course explained in exquisite details
Chloe Garcia
Excellent course. All technical information regarding valves are explained in great detail. Animations help explain the various valve types and how they work. Also at the end of the course someone can download some very useful calculation tools.
Nikolaos Patronis
This was my first course with WR Training. I picked a subject I know fairly well so that I could gauge how good the courses were. I have gained further knowledge and good resources to come back to another time. I will be booking another course in the near future
