Inherent equal percentage
characteristic
Disk design has a signicant
effect on buttery valve ow rate
as the valve travels from closed
to open. A disk with an inherent
equal percentage characteristic
can compensate for changing
pressure drops as the ow
changes.
Installed linear characteristic
Only equal percentage trim will
give a linear installed characteristic
for changing pressure drops,
which is ideal. The result is a more
accurate, one-to-one change
between ow rate and valve travel,
i.e. a linear installed characteristic.
Wide control range
The range of travel over which
process gain stays between 0.5 to
2.0 is dened as a valve’s control
range. Outside of this range good
control is lost. The Control-Disk
valve provides excellent throttling
control in the 15 to 70 percent
valve travel range.
Wide control range to keep quality on spec and output on target.
