ABSTRACT:
A self-aligning valve disc assembly for a fluid regulator valve. A disc holder includes a central, raised protrusion enabled in one embodiment by a cone-shaped floor surface for providing a single point of contact with a disc. The single contact point provides a pivoting action with a point of force inside the diameter of the opposing force of the valve seat. This enables the pivoting action of the disc to self-align the disc to the seating surface so as to reduce the forces required for the regulator to function properly.
