Voith Paper: Accuracy and quality improved with field instrument partnership
Voith Paper Automation GmbH & Co. KG and ABB Automation Products GmbH
signed a framework agreement in 2008 covering the field instrument segment. Since
then, ABB has been producing select positioners and differential pressure
transducers exclusively for Voith. During the decision-making process for the
products careful attention was paid to ensuring their optimum suitability for use in the
papermaking process. Voith Paper uses these products from the stock preparation,
to the approach flow system, all the way to the steam and condensate system.
A detailed test conducted at the Voith Paper Technology Center (PTC) in
Heidenheim recently demonstrated the technical advantages of the OnC ValvePos
500 positioner. When used in the subsequent starch dilution, it was possible to
improve the control accuracy and quality considerably.
In the original installation, there was a continual oscillation of the flow rate in the
range of 20 L/min which made a constant readjustment necessary.
The same valve in the same installation location but with the Voith OnC ValvePos
500 positioner demonstrated considerably more stable control behavior. Here, the
flow rate control was not modified.

for control interventions both in the travel distance as well as on the time axis. Thus,
the flow rate value fluctuated only in the range of 2 L/min. With the OnC ValvePos
500 it was possible to reduce fluctuations by a factor of 10.
Retrofitting the Voith OnC ValvePos 500 positioner therefore increases stability and
accuracy in the paper-making process. In addition, the cost of maintenance is
reduced since the life of the control fittings is extended considerably. As a result,
maintenance costs can be greatly reduced over the life of the field instruments.
Furthermore, there is a significant potential to save energy, mainly in the steam
circuit.
These results have encouraged Voith Paper Automation to continue collaborating
exclusively with companies that are on the cutting edge of technology. Since 2007,
Voith Paper Automation has extended the product portfolio with the “Field Instrument
Initiative” and offers a variety of valves and sensors. All important field instruments
can therefore be provided by a single supplier. In addition to the technological
advantages, the modular designed valves and sensors offer savings advantages as
well. In this way it is possible, for example, to use identical positioners, limit switches
and actuators for a variety of control and on/off valves (ball valves, hard and soft-
seated butterfly valves, ball segment valves). In turn, this reduces the need for spare
parts, making the procurement of the spare parts more cost-efficient overall.
Voith Paper is a Division of the Voith Group and the leading partner to and a pioneer
in the paper industry. Thanks to continuous innovation, Voith Paper optimizes the
paper production process, focusing on the development of resource-saving products
to reduce the consumption of energy, water and fibers.
Voith was founded on January 1, 1867 and has set new standards in the fields of
paper, energy, mobility and service. With annual sales of EUR 4.9 billion, 43,000
employees and more than 290 locations worldwide, Voith is one of the large family-
owned companies in Europe. Voith is the official partner to the initiative "Germany -
The Land of Ideas".
