Selection of control valves
Thread Content
What are the main factors considered when selecting the flow characteristic of a control valve? Control requirements? Should it still be the design institute that selects it based on the control requirements of this control system?
Mainly object characteristics and process control requirements； Secondly, the current level of technology in control valves determines that, in situations such as high pressure differences, linear or nearly linear behavior is often the only option; their design and materials are primarily aimed at handling flashing and cavitation, even though an isocvolumetric flow characteristic would be ideal.
