Abstract: A valve arrangement for improved high frequency performance comprises: a valve seat member adapted in size and shape to define a valve seat and a flow-through opening; a valve member adapted to be displaceable relative the valve seat along a displacement axis during use in response to a damping fluid pressure force overcoming an opening force threshold, wherein the damping fluid pressure force is provided by damping fluid pressure acting on an inlet side of the valve member, the opening force threshold being at least partly adjustable by a force actuator, wherein the valve member and the valve seat member are adapted to provide a chamfer restriction provided with an opening cross-section which decreases from an inner lateral position to an outer lateral position relative the displacement axis. A shock absorber comprising the valve arrangement and a method for adjusting damping fluid flow are disclosed.
