Abstract: A screw-in cartridge valve for the employment in the field of high pressure hydraulic includes a valve housing having an exterior screw-in thread section extending between a low pressure or ambient pressure area and a high pressure area, said valve housing comprising a pressure balance path connecting both pressure areas with one another. In a screw-in cartridge valve assembly including a basic body having a threaded bore for said valve housing of said screw-in cartridge valve and including a sealing ring in said low pressure or ambient area activated by means of the thread tightening tension between both pressure areas at least one pressure balance path is provided by means of which the pressure acting in the high pressure area on said exterior thread section is transmitted into the low pressure or ambient pressure area of said exterior thread section.
