Positioners
Split Ranging with Positioners
Positioners are sometimes used to “Split-Range” two control
valves in a parallel configuration within a piping scheme.
This technique is used to obtain higher rangeability than could
other
wise be achieved with a single control valve. T
ypically one
smaller valve supplying 15% to 35% of total flow is mated with
a larger valve supplying 65% to 85% of total flow
.
The best-matched pair will each be providing similar rangeability
for each respective flow contribution to the manifold. Calculated
as maximum flow /minimum controllable flow
, the smaller valve
should not be attempting to control flow below 5% of stroke.
Estimate Cv from Cv tables vs. stroke to calculate this.
The chosen positioners would then have a Low Range signal
for the smaller valve and a High Range Signal for the larger
valve. With this, a single control signal can be sequentially
applied to each valve. At mid-signal range, the little valve is
completely open while the larger valve is just starting to open.
Controllability for wide process set point ranges is
dramatically improved.
