ABSTRACT:
A control valve (1) comprises a housing (2) manufactured by a pressure die casting process, whose housing edges of upper semicircular bore hole are located exactly vertically above housing edges of lower semicircular bore hole and for this reason, the mold slide that forms the control edges (21) no longer has any contact point with the housing (2) and, as a consequence, symmetrical control edges (21) arise.
