Pressure regulators with pivotable valve disk assemblies

Abstract

Pressure regulators with pivotable valve disk assemblies are disclosed. An example pressure regulator includes a valve body defining a fluid passageway between an inlet and an outlet, a seat positioned in the fluid passageway, a stem movable relative to the seat, and a disk assembly coupled to the stem, the disk assembly including a disk holder, an inner surface of the disk holder defining a cavity, a disk positioned in the cavity, the disk pivotable with respect to the disk holder to sealably engage the seat, and an alignment ring positioned between the inner surface and the disk, the alignment ring to provide a seal between the disk and the disk holder, the disk to compress the alignment ring when the disk pivots from a neutral position with respect to the disk holder, the alignment ring to bias the disk to the neutral position.
