Abstract

The invention relates to valve arrangement for controlling hydraulic components such as power cylinders, hydraulic engines, which valve arrangement comprises a directional valve (10) with connecting channels (18) and (19) wherein said directional valve is arranged to control the flow direction of a fluid in said channels (18, 19). According the invention a number of first and second dual port shut off valves of the seat type (20a, 30a, 40a, 20b, 30b, 40b) are connected to said channels. These dual port shut off valves are connectable to a hydraulic component for controlling said component. The valve arrangement further comprises a manoeuvring unit (60) for activation of the directional valve (10) and the dual port shut off valves.
