The arrangement and method comprise, during an active control mode, pressure relieving (AM S) the control valve member and applying an actuating force (AM S) for controlling the pilot pressure (Pp). Further, during a failsafe control mode, controlling (FM S) the control valve member by means of the pilot pressure (P). And finally, during both the active control mode and the failsafe control mode restricting (S) the pilot fluid flow (PF, PF) by at least one common valve seat (R).
