A pressure valve, especially a pressure-limiting valve, pressure-reducing valve or the like, has an insertion body (3), which can be inserted into a hollow valve body, especially into a valve housing (1), and can be positioned on a stop collar (6) on the valve body, an attachment body (8), which can be arranged axially with respect to the insertion body, is used to fix said insertion body in the valve body, has an attachment screw connection (9), and is connected in a positively-locking manner to the insertion body at least in the installed state, and a valve body (11) which has a valve seat and can be clamped in between the insertion body and the attachment body. In order to make the parts which are located between the insertion body and the attachment body accessible, the insertion body and the attachment body can be connected to one another by means of a coupling screw connection (36, 37). Provided behind the individual threads of the coupling screw connection there is in each case one undercut (38, 39) for non-touching engagement of the other individual thread which is longer in the axial direction than the individual thread engaging therein (Fig. 1). <IMAGE>
