Control valve, elbow
Thread Content
Dear sea friends: What are the pressure drops respectively when the fluid flows through the control valve and the elbow?
Not necessarily; different valves have different ones
The pressure drop of control valves can set constraints for the automation team; the pressure drop at elbows is related to the pipe diameter.
Poster, take a look at the post below; I have replied to it with a brief introduction to the calculation of pressure drop for valves and elbows. I hope it will be helpful to you. http://bbs.hcbbs.com/viewthread.php?tid=407242&page=1#pid2173685
The medium, temperature, and pipe material all play a role.
I encountered a similar problem today; the pressures before and after the control valve depend on the pressures of the pipeline equipment located before and after it. For example, you must not exceed the safe pressure limit set by the downstream equipment； Then determine the pressure drop of the control valve, thereby determining the pressure drop for the instrumentation department!
