Abstract: A method for joining a valve member for use within a valve, the method including brazing a body portion having a head and a base, the base having a bore extending a depth therein, to a leg portion having a shaft, the shaft having a distal end, a proximal end opposite the distal end, and a plurality of legs extending radially and axially therefrom and away from the proximal end, the brazing including placing a braze material between the bore and the proximal end, inserting the proximal end into the bore such that a portion of an outer surface of the proximal end is adjacent to an inner surface of the bore, and heating at least the adjacent surfaces to a braze temperature.
