4.3 Functional Principle
The pneumatic part of the dosing valve is controlled by a 5/2-way valve. This initiates the grease dosing. The
dosing pressure depends on the lubricant feed pressure (medium).
In order to obtain a high quality and repeatability of the dosing process, the complete cycle must be complet-
ed. This means that the control piston must be driven from the starting position to the dosing position and
then back to the starting position.
