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, x) serves for the actuation of the control slide (). Since the actuating pressures (x, x) also actuate a logic valve, which in turn influences an additional valve, and/or actuates a pressure compensator connected upstream to the control valve (), the difference of the two actuating pressures (x, x) initially displaces the control slide of the control valve. The higher or the lower of the two actuating pressures (x, x) either actuate the further valve in the form of the additional valve, and/or influences the pressure compensator.
