How much do I need to turn the lever to cut off 50% of water flow in 2" copper pipe?
1) exactly turn half between Full open and Full close position?
or
2) 10% more towards close-side than half position?
or
3) 10% less toward open-side than half position?
as you know, the shape of ball in the pipe rotate to open and close, so if turn middle, then how much it actually shut-off?
Thanks
