An anti-cavitation cage for a valve assembly. The anti-cavitation cage includes a body having a plurality of slots, a first end, and a second end. At least one slot of the plurality of slots includes an inside surface having a lattice structure. The lattice structure is one of uniform in grade through the at least one slot or a graded type of lattice structure varying in density from a first portion to a second portion. The anti-cavitation cage having these features is a single component.

Anti-cavitation cage for valve assembly and method of manufacture

A valve trim assembly configured to be disposed in a fluid flow control valve, including, a valve seat adapted to be disposed in a fluid passageway of the fluid flow control valve. The valve seat includes an annular flange and a seating surface spaced from the annular flange. The valve trim assembly additionally includes a fluid control member movable relative to the valve seat to control fluid flow through the fluid passageway, wherein the fluid control member is movable from a closed position, in which the fluid control member sealingly engages the seating surface of the valve seat, and an open position, in which the fluid control member is spaced from the seating surface, by moving the fluid control member away from the annular flange of the valve seat.

Push-down-to-open high recovery choke valves

Example fluid valves having non-circular flow passageways are disclosed. An example fluid valve includes a body defining a fluid passageway between an inlet and an outlet, at least a portion of the fluid passageway between the inlet and the outlet has a generally non-circular cross-sectional shape when taken along a plane transverse to a direction of fluid flow, the cross-sectional shape includes a curved central axis, with outwardly curved end walls and curved lateral walls joining the curved end walls.
