When selecting a control valve, how do you distinguish between linear and equal percentage control, and what are the differences between them? Solve

The 2L picture is very illustrative. I’m not quite sure which component in the valve this is, so I’d like to ask everyone for advice

What is shown is the spool cage of the control valve, which determines the fixed travel range for the up and down movement of the spool; air intake occurs through the openings on the sides. I think what he means is to judge based on the curve, after all I have seen different types of openings. You can check my post on natural gas-derived monomer S, which contains photos from the site.

Is there any specific comparison and analysis available regarding percentage-based flow and linear flow?

A quick-open valve is a on/off valve; so how should one decide whether to use a linear or equal percentage control valve for specific operating conditions?

To use automation, select a proportional valve. Manual randomness.

The 2l curve QO corresponds to the stop valve, right?
