Abstract

A valve arrangement has an adjustable control valve including a control slide for actuating at least one consumer connection (A, B) and an LS control line. The differential pressure of two actuating pressures (x a , x b ) serves for the actuation of the control slide. Since the actuating pressures (x a , x b ) also …
