Does a reduced port ball valve have much if any effect on flow?
My understanding is that the port reduction has an effect on water, but no so much on gas. Is this correct?
I can’t find anything regarding this in the National code, and when my local gas company made the connection between my 3/4” riser/regulator and my 3/4”entrance line they pieced in a 1/2” shutoff.
Thanks
