Abstract

A handling line that includes a valve in a feed line that sets the valve to a respective opening position (s) for adjusting a coolant flow (F) to a metal strip per unit of time; an upstream condition detection device upstream of the valve device in the feed line that detects an upstream condition (ZV) of the coolant; a control unit that determines a set point (s*) for an opening position (s) of the valve device corresponding to the set point (F*) for the coolant flow (F) based on a set point (F*) for the coolant flow (F*), the upstream condition (ZV) of the coolant and a valve characteristic (C) of the valve device.
