A radiation shielding overlay for a portion of a valve controller or a valve assembly. The radiation shielding overlay includes a layer including a base material and a second material infused within the base material. The base material has a first density and the second material has a second density higher than the first density, increasing a density of the layer. The layer is adapted to be disposed over a surface of a housing of a valve controller or a valve assembly, such that the layer blocks radiation from reaching a component disposed within the housing.

Radiation shielding overlay and method of manufacture

A diffuser has a cylindrical wall and an arcuate end wall located at an end of the cylindrical wall. The cylindrical wall has a first lattice structure formed of a first plurality of triply periodic surfaces that are periodic in cylindrical coordinates, the first lattice structure having a plurality of passages that extend between an inner surface of the cylindrical wall and an outer surface of the cylindrical wall. The arcuate end wall has a second lattice structure formed of a second plurality of triply periodic surfaces that are periodic in spherical coordinates, the second lattice structure having a plurality of passages that extend between an inner surface of the arcuate end wall and an outer surface of the arcuate end wall.

Diffuser

A control valve has a trim assembly to condition the flow of fluid through the control valve and, in some applications, to provide guidance for a valve plug. The trim assembly has a lattice structure formed of a plurality of triply periodic surfaces that form a plurality of passages that extend between an inner surface of the circumferential wall and an outer surface of the circumferential wall.
