Abstract
A valve arrangement regulates a pressure in a hydraulic fluid flow in a valve device in response to an actuating force during an active control operation and mechanically regulates the pressure during a fail-safe operation when no actuating force is present. The valve arrangement comprises a first spring member adapted to be arranged in a valve chamber of the valve device to interact with a valve seat to provide a first restriction by which the hydraulic fluid flow is restricted during active control operation, and a second spring member adapted to be arranged in the valve chamber to provide a second restriction by which the hydraulic fluid flow is restricted during fail-safe operation. During active control operation, an active control flow channel is open. During fail-safe operation, the active control flow channel is substantially closed by means of the first spring member.
