摘要： Fluid valve control members having contoured sealing surfaces and methods of making the same are disclosed. An example fluid valve control member includes a body portion having a sealing surface configured to engage a sealing ring within a fluid control valve. A first portion of the sealing surface has a first spherical radius with respect to a first point along a centerline of the body portion and a second portion of the sealing surface has a second spherical radius with respect to a second point along the centerline of the body portion. The first and second points are offset from each other and the second spherical radius is sized to be smaller than the first spherical radius to form a substantially seamless transition between the first and second portions of the sealing surface.
