thank you gents for this information
actually i'm process engineer,and if there are any checks you advise me to check before keeping this valve partially closed i welcome
the valve will be closed 50% and still on this position for ever
pressure drop is 3 bar
delta T =5 degrees
valve material
ball is SS
seat PFTE

i have reduced bore ball valve and i'm opening it partially,not fully open.
prssure differential acroos the valve is 3 bar
ball material is SS316
seat PTFE
any body know is that going to affect the valve,can i keep partially open?
