The Minimum Flow is calcu-
lated from the minimum
recommended pressure drop
1 ft. WG (=3.0 kPa)
The Nominal Flow is from the
maximum setting of the valve
and the minimum recom-
mended pressure drop,
2 ft WG (=6.0 kPa)
The Max Flow is calculated
from the maximum setting of
the valve and the max pressure
drop, 20 ft WG (=60.0 kPa)
