摘要

The control system for a multiplicity of valves for the simultaneous dispensing of a liquid into a system of lines with a multiplicty of connected consuming units, in particular for the zone-wise distribution of cooling fluid by means of spraying devices to the rolls of a rolling mill in the context of the flatness control of fine strips operates in such a way that the valves (3) to be opened or closed are opened and closed one after the other in a certain time. The valves (3) are actuated in a predetermined sequence. IMAGE
