how to select the control valves?

advertisement

• One important requirement in selecting the right control valve is ensuring that the valve has the proper installed characteristic and process gain

• Process gain has been identified as an important characteristic; see work by Greg McMillan or Emerson’s Mark Coughran or EnTech paper

• We’ll see how to develop a model to evaluate control valve performance

• We’ll look at some examples of modeling techniques to help us analyze control valves
