13.5.3.8 Valve Position Histogram

Valve position histogram trend can be used to determine

valve operation points. The trend shows if the valve is work

ing as real control valve and how wide the operation area

is. This information can also be used to verify valve sizing.

•

The histogram is updated all the time when the

device is powered

•

Divided into 12 subranges, 1st and 12th subrange

represent closed and open positions.

•

Valve is closed if position < 1 %

•

Valve is open if position > 99 %

Valve position histogram trend shows two measured valve

position histograms side by side: lifetime history of the valve

position and the last three months. If the valve operation

point has recently changed it can be seen in three months

histogram.

Valve position histogram trend is especially useful when

optimizing plant operation or replacing old control valves.

•

If valve operation point is 8090 % most of the

time, then the valve could be too small for current

application

•

If valve operation point is 1030 % most of the

time, then the valve could be too big for current

application

•

Under normal process conditions, the ideal control

area is 3080 % (depends on valve type). If there is a

need to define more accurate min. and max. values

that can be done with Nelprof.

•

Real working point should be checked with the

installed flow curve with Nelprof.

This trend also shows if a valve is in on/off use. This means

if a valve is fully closed or fully open most of the time. If you

can see that a valve has been between 5070 % for most

of the time and that counters are showing that there are a

lot of travels and reversals, there might be wearing in the

valve or seals and/or actuator on that position.
