ABSTRACT:
A valve for dispensing a predetermined amount of molten lead to the mold of a battery grid casting machine has two tubular housings arranged in telescoping relation with their axes extending vertically. The upper housing is fixed and has a feed line for molten metal connected thereto. The lower housing is vertically movable and has a molten metal discharge line extending therefrom. A ball valve member is retained on a pedestal in the lower housing and is arranged to seal with an annular valve seat in the upper housing to control the flow of metal in response to vertical movement of the lower housing. The ball valve is retained in axial alignment with the valve seat by a plurality of circumferentially arranged fingers on the upper housing which surround and extend downwardly beyond said seat.
