The invention relates to a magnetic valve in which the electromagnet is housed in a chamber which is not infiltrated by the pressure medium to be controlled, and in which a rod coupling is effective between the armature of the electromagnet and the closure body of the valve inserted between a pressure source and a pressure consumer, and in which a sealing apparatus is provided which seals the entryway of the rod coupling into the region infiltrated by pressure medium. Furthermore, the consumer through the operation of a slider valve is connectable firstly to a low-pressure chamber, secondly to a position to break flow and thirdly to a high-pressure chamber. In addition, the slider valve is controllable into two different energized positions through the use of plural spring elements and the electromagnet can be subjected to varying electrical output to attain an intermediate or final position.
