How is the resistance coefficient of a control valve determined?
Thread Content
As the title suggests, how is the resistance coefficient of a control valve at different opening degrees determined?
Please give some support; I’m asking the experts here for help
It was tested; there is no calculation method
For a specific model of control valve, can it be found in its manual?
It can’t be found; to be honest, many factories themselves don’t even know about it
Wow, does that mean it’s still not possible to calculate the pipeline characteristic curves at different opening degrees of the control valve?
There is a curve in the Valve Design Manual compiled by Lu Peiwen; if you follow that curve, no one knows whether it will be accurate or not.
