A hydraulic steering arrangement (1) including a supply port (2), a return port (4), a working port arrangement having two working ports (5, 6), a main flow path (7) between the supply port (2) and one of the working ports (5) and a return flow path (8) between the other working port (6) and the return port (4), wherein the main flow path (7) includes a main orifice (A1), a flow meter (9), a first flow meter orifice (A2) upstream the flow meter (9), a second flow meter orifice (A3) downstream the flow meter (9), and a first working port orifice (A4), the return flow path (8) includes a second working port orifice (A5), a load sensing point (17) is arranged between the main orifice (A1) and the first flow meter orifice (A2), a drain orifice (Ad) is arranged between the load sensing point (17) and the return port (4), and a priority valve arrangement (10) is arranged between the supply port (2) and the main orifice (A1). Such a steering arrangement should enable a high steering speed without loss of comfort. To this end a load sensing port (16) of the priority valve arrangement (10) is connected to the load sensing point (17), characterized in that a priority outlet (CF) of the priority valve arrangement (10) is directly connected to the main orifice (A1), the load sensing port (16) of the priority valve arrangement (10) is directly connected to the load sensing point (17) and the main flow path (7) includes a check valve (24) between the load sensing point (17) and the working port (5) of the main flow path (7), the check valve (24) opening in a direction towards the working port (5).
