Abstract:
An electrohydraulic valve assembly having an inflow channel, a working channel and an outflow channel, including first and second valves each having a magnetic regulating device for applying a regulated activation force to the respective valve. The valves are arranged in parallel so that either can provide the hydraulic connection between the inflow, working and outflow channels. In the case of error detection, the active valve is deactivated and the until then passive valve is activated and vice-versa. The deactivating of a valve device moves the valve piston to a hydraulic neutral position by means of a second stage.
