A valve arrangement comprising a main valve member being axially movably arranged in a valve housing and arranged to interact with a main valve seat of the valve housing in order to restrict or regulate a pressure in a main fluid flow in response to a pilot pressure acting on the main valve member. A control valve member is axially movable within the main valve member in response to an actuating force acting on the control valve member. A pilot valve member is axially movable within the control valve member, and is arranged to interact with a pilot valve seat of the control valve member to restrict a pilot fluid flow out from a pilot chamber. The pilot valve member is resiliently loaded towards the pilot valve seat relative the main valve member or the valve housing, such that the resilient loading on the pilot valve member is adjustable in response to the actuating force. |
