A tubular valve housing includes a guide body for pressure fluid that is disposed between a valve body having a hollow-conical valve seat and a chamber of the valve housing, in which actuating means of the valve are received in the chamber. The guide body is penetrated by a closing body of the valve which divides the chamber from an annular conduit. The annular conduit carries the pressure fluid and communicates with the valve seat and has circumferential outlet openings of the valve housing. The guide body is braced on the valve body, with a face end contacting the valve body, and has guide conduits, fitting over an outline of the valve seat, which on the outlet side discharge into the annular conduit. The face end of the closing body, which cooperates with the valve seat, is a spherical portion that makes a transition with sharp edges to the cylindrical shaft of the closing body. With the guide body, the stream of pressure fluid emerging from the valve seat is diverted into the annular conduit, so that flow instabilities are largely without any effect on the chamber of the valve. The valve can be used in brake systems of motor vehicles.
