ABSTRACT:
A flow control valve including a movable part and a housing for accommodating the movable part may be produced by molding the components in sequential steps. Preferably, the housing is molded in a first step and the movable part is molded in an at least partially closed position in a second step in the same mold. This method enables the surface of the housing to serve as at least a portion of the mold for forming a substantially sealing portion of the movable part such that a very close tolerance between these components is achieved. The movable part is preferably a butterfly disc and the housing is preferably a butterfly valve housing.
