摘要： The disclosure relates to a unitary disc-stem apparatus for a valve, which has a disc defining a circumference around the disc; a first hub integral to the disc; a second hub integral to the disc; a first stem portion joining the disc at the first hub and a second stem portion joining to the disc at the second hub; a curved extended edge which is transposed on opposite sides of the disc, wherein the curved extended edge is progressively longer moving circumferentially away from the first hub and the second hub along the circumference of the disc, and longest at a position where the opposite curved extended edges of the disc are along an axis perpendicular to the first stem portion and the second stem portion.
