NOTE!
A correction factor must be applied when the valve is smaller than the supply
pipe.
When dimensioning the valve a correction factor must be included for the re-
duction from a larger supply pipe to a smaller valve, see Fig 13. The calculated
capacity factor K
v
(C
v
) is multiplied by the correction factor. The correction fac-
tor is determined by the degree of reduction.
