Good cross profiles and short engagement times
Installing OnQ ModuleTap actuators ensures the highest consistent quality of the basis weight cross profile in headboxes with dilution valves (ball valves).
With OnQ ModuleTap, a consistently high basis weight profile quality is guaranteed by means of a rotary motion (0-90°) on the basis of the profiles measured. The combination of OnQ Profilmatic control software and the OnQ ModuleTap actuator system provides good and stable basis weight cross profiles and short engagement times until reaching the guaranteed quality values after downtimes, grade changes or breaks.
OnQ ModuleTap is used in headboxes where dilution water dosing is carried out via ball valves. The automatic control system is especially suitable for retrofitting headboxes from various manufacturers that have no dilution water system.
