Zusammenfassung:	PCT No. PCT/EP96/00637 Sec. 371 Date Jan. 12, 1997 Sec. 102(e) Date Jan. 12, 1997 PCT Filed Feb. 14, 1996 PCT Pub. No. WO96/31300 PCT Pub. Date Oct. 10, 1996To produce a two-part valve housing inexpensively it is proposed to produce from a sleeve-shaped blank (20) by internal high-pressure forming an intermediate product (10) which corresponds to the first housing part in a section lying on one side of a separating surface (T) and to the second housing part in a section lying on the other side of the separating surface (T). Connection sections (24, 32), adjacent to the separating surface, of the intermediate product (20) have different diameters so that cooperating threads by means of which the housing parts are screwed together can be produced on them.
