Hydraulic arrangement

A hydraulic arrangement comprising a supply port, a return port, a working port arrangement, and a valve controlling a supply of hydraulic fluid from the supply port to the working port arrangement, wherein the valve comprises a housing and a spool movable in lengthwise direction in the housing and forming together with the housing at least one flow path the resistance of which depends on the position of the spool in the housing, and the spool is actuated by a hydraulic pilot pressure in a pressure chamber, wherein the housing comprises a pilot pressure relief port connected to the return port via a shut-off valve and the spool after a predetermined stroke opens a connection between the pressure chamber and the pilot pressure relief port,

• wherein the spool is movable in two directions opposite to each other, wherein a pressure chamber is provided for each direction of stroke, and wherein the spool after a predetermined stroke in one direction opens a connection between one of the pressure chambers and the pilot pressure relief port and the spool after a predetermined stroke in the other direction opens a connection between the other of the pressure chambers and the pilot pressure relief port.
