I think the valve will remain open till defferential pressure is maintained 20 bar. Whenever there is a change in pressure either upstream or downstream the valve will close thus it maintains 20 bar pressure in the line. Is my understanding correct.
Sir could you please draw the one p&id source to the destination to transfer the water as an interview poin mode. Including Nrv, reducer, strain, valve

Please make one video on different types of pump characteristic curves
What is criteria of accentric and concentric flange to control valve.
I have covered that topic in the reducer and expander video
Sir please make a video on utility system ( offsites)

Sure
The valve may fail or get damaged due to the excessive pressure. This could result in leakage, which can be unsafe and lead to system failures.
How to calculate shut off pressure of control valve
We will make the video soon about it
Design pressure -downstream pressure am I correct
Control valve will not close becos the shut off pressure 40 bar is higher than 20 bar design oressure of the valve
please make videos in hindi🙏
