摘要： A gas flow regulator valve is provided with a metering valve and filter assembly including a drawn, generally cup shaped, or hat shaped filter element having a substantially flat end panel, a generally cylindrical sidewall and an open end opposite the end panel. An integrally formed flange, or rim, is formed around the open end and projects outwardly therefrom to provide means for mounting the filter, in a fluid-tight relation, in the metering valve assembly body. The filter is formed from a substantially planar disc-shaped blank of a multilayered screen material in which the respective layers are welded, or sintered, to one another to form a rigid, porous filter medium. The blank is shaped by a cup drawing operation of a filter mesh made of layers of woven smooth, corrosion resistant, fine gauge, high strength metal.
