Abstract:
The present invention relates to a two-stage valve for controlling fluids, in particular a hydraulic fluid. The valve includes an actuating element, a pilot stage having a first valve seat and a first closing body, which is connected to the actuating element, and a main stage having a second valve seat and a second closing body. The second closing body is provided with a fastening region and a main region having a passage opening. The first valve seat is arranged at the passage opening. The second closing body is connected to the actuating element via the fastening region. The fastening region is designed elastically in such a way as to open the pilot stage by elastically deforming during actuation of the actuating element.
