Abstract
The invention relates to a valve, in particular a proportional pressure regulating valve, comprising a valve housing () and a valve piston () which is arranged in the valve housing in a longitudinal a movable manner and which can be actuated by means of an actuation magnet () so as to produce either a fluidic connection between a pressure supply connection (P) and a load connection (A) or between the load connection (A) and a return connection (T) in the valve housing (), wherein the valve piston () is permanently fluidically connected to the return connection (T) at the opposing end faces () of the valve piston. The invention is characterized in that the valve piston () has a pressure-active measuring surface () in the region of the load connection (A), said pressure-active measuring surface providing the respective fluid pressure at the load connection (A) as a counterforce to the actuation force of the actuation magnet () when the actuation magnet () is energized in order to produce a fluidic connection between the pressure supply connection (P) and the load connection (A).
