Beschreibung
Zusammenfassung:	A hydraulic valve arrangement (1) is described comprising a supply port arrangement having a pressure port (P) and a tank port (T),a working port arrangement having at least a working port (A, B), a main valve (2), and a compensation valve (3), said compensation valve (3) being arranged between said pressure port (P) and a pressure channel (4) connected to said main valve (2), said compensation valve (3) forming a variable orifice between said pressure port (P) and said pressure channel (4). The control behavior of the compensation valve should be extended. To this end said compensation valve (3) is adjustable to connect said pressure channel (4) to said tank port (T).
