Abstract

A radiator valve having an enclosed pre-adjustment arrangement. In the valve body (10) a plastic insert (36) is disposed, having a coaxial, conical inner surface (38) and a projection (40) provided with a flow opening (34). The flow opening is made with a desired accuracy of size and surface smoothness. The pre-adjustment spindle (12) has a conical member (44), including a shield member (52), the height of which increases continuously. The shield member (52) is adjusted in order to cover up a larger or a smaller portion of the flow opening (34) and is locked by means of a tightening nut (62).
