Abstract
The disclosure relates to a valve, comprising a main piston for actuating a main volumetric flow and a pilot piston for actuating a pilot volumetric flow. The main piston and the pilot piston are guided in a valve housing in a longitudinally movable manner, and the pilot piston can be actuated using a magnetic device. The position of the main piston can be set using the pilot piston in that a fluid pressure acting on the main piston is signalled via a fluidic connection into a pilot chamber comprising the pilot piston which keeps the main piston in the closed position thereof, said closed position cutting of the main volumetric flow.
