The valve is formed by cold forming a blank into an elongated cup having an extremely thin wall and a flared open end onto which a cap is welded, the bottom end of the cup which defines the tip end of the valve having a wall section which is substantially of the thickness of the original blank. In accordance with one aspect of the invention, a keeper groove is formed adjacent the tip end as part of the cold forming process.
