Abstract (en)
[origin: WO2008116515A1] The invention relates to a valve arrangement having an adjustable control valve (10), comprising a control slide (12) for actuating at least one consumer connection (A,B), and having an LS control line, wherein the differential pressure of two actuating pressures (X<SUB>a</SUB>, X<SUB>b</SUB>) serves for the actuation of the control slide (12). Due to the fact that the actuating pressures (X<SUB>a</SUB>, X<SUB>b</SUB>) also actuate a logic valve, which in turn influences an additional valve, and/or actuates a pressure scale that is connected upstream to the control valve (10) having the control slide (12), the difference of the two actuating pressures (X<SUB>a</SUB>, X<SUB>b</SUB>) initially displaces the control slide of the control valve, wherein the higher or the lower of the two actuating pressures (X<SUB>a</SUB>, X<SUB>b</SUB>) either actuate the further valve in the form of the additional valve, and/or influences the pressure scale.
