Abstract (en)

[origin: WO2007071612A1] The invention relates to the use of a piezo nozzle system in a paper machine. Contrary to all expectations, piezo nozzle systems have proven to be particularly suitable for use in the extreme ambient conditions of a paper machine. Despite the high degree of humidity, the use of piezo nozzle systems allows a high degree of control and dynamics to be achieved when using controlled or regulated valve devices in a paper machine. Furthermore, the use of piezo nozzle systems ensures a high availability and stability of the valve devices while having a robust and extemely compact design.
