Abstract: A valve arrangement comprising a valve housing, a pilot chamber, a main valve member and a control valve member. The main valve member is axially movably arranged in the valve housing and is arranged to restrict a main fluid flow.

The control valve member is arranged to interact with the main valve member to define axially separated pilot and bypass fluid restrictions. The pilot restriction restricts a pilot fluid flow out from the pilot chamber. The bypass restriction restricts a bypass flow bypassing the main fluid flow. The bypass flow is separate from the pilot fluid flow. The pilot and bypass restrictions are adjustable in response to the actuating force, thereby allowing simultaneous adjustment of the pilot pressure and the bypass fluid flow.
