  • Patent number: 10458555
    Abstract: A control valve includes a body having an inlet and an outlet and a valve seat positioned in a passageway between the inlet and the outlet. A valve plug is positioned within the body and is movable between an opened position and a closed position to modulate a fluid flow at the outlet. A cage is disposed within the body adjacent the valve seat and proximate the valve plug and has a circumferential wall having an outer surface and an inner surface aligned along a longitudinal axis of the cage. The outer surface of the cage defines an outer flow length and the inner surface defines an inner flow length that is less than the outer flow length.

  • Publication number: 20180340616
    Abstract: A unitary valve trim assembly that can be easily installed in and removed from a valve body of a process control valve. The valve trim assembly includes a valve cage and a valve seat. The valve cage has a first projection that extends in a first direction that is perpendicular to a longitudinal axis of the valve cage. The valve seat has a second projection that extends in a second direction, opposite the first direction, that is perpendicular to the longitudinal axis. The second projection is arranged to engage the first projection to removably couple the valve seat to the valve cage.

  • Patent number: 8550117
    Abstract: A seal assembly for a fluid pressure control device includes a guide element having a sealing surface and a first guide surface. A throttling element assembly includes a throttling element positionable within a fluid flow path, the assembly defines a mating surface adapted to seal with the sealing surface, and a second guide surface sized to slidingly engage the first guide surface. A relief void is formed in at least one of the guide element and the throttling element assembly adjacent the first and second guide surfaces to receive loose solid material, to thereby prevent disruption of the seal formed between the sealing surface and the mating surface.

  • Patent number: 8430131
    Abstract: A stackable noise attenuating disk includes an inner perimeter edge and an outer perimeter edge. A plurality of inlet passages is disposed along the inner perimeter edge and a plurality of outlet passages is disposed along the outer perimeter edge. The plurality of outlet passages includes a plurality of first outlet passages and a plurality of second outlet passages. Each of the plurality of first outlet passages have a first width and each of the plurality of second outlet passages have a second width that is greater than the first width.
