Control Valve: Hydraulics, Characteristics and Sizing

Know more about control valve characteristics, hydraulics, calculate its pressure drop and choose its controlling cases

Control valves are an essential part of any process plant. You can hardly see a process plant whether in oil and gas industry or in any chemical processing plant without a control valve as they are used to control more than 95% of process parameters.

What you’ll learn

  • The main functions of a control valve in a process.
  • How a control valve works?.
  • The valve flow coefficient.
  • Valve inherent and installed characteristics.
  • Calculate control valve main parameters and controlling cases.

Control Valve: Hydraulics, Characteristics and Sizing

Requirements

  • Basics of chemical engineering, if you are still a student, this course will help as well.

Control valves are an essential part of any process plant. You can hardly see a process plant whether in oil and gas industry or in any chemical processing plant without a control valve as they are used to control more than 95% of process parameters.

Throughout this course, we shall see the main functions of a control valve and how they work,

We shall go in deep on what is a control valve Cv or flow coefficient and how it is important in sizing and rating of a control valve.

We shall go through control valve inherent and installed characteristics and how the process configuration affects the operation of a control valve and what is the difference between inherent and installed characteristics.

Then we shall see when to use a butterfly valve as a control valve and how the valve geometry affects its characteristics.

Finally, we shall go through the valve sizing procedure, how to choose the controlling case, we shall go through more than one example, carry out calculations and you shall have an excel sheet that can guide you in the future.

These examples will teach you not only how to calculate the pressure drop of the control valve or how to choose the cases that shall affect the valve sizing, they shall even show how the whole system hydraulics interact with each other and the means to debottleneck it.

Waiting to see you in the course and let’s start.
