Abstract: A method of manufacturing a body of a fluid control apparatus using additive manufacturing, the method including forming an inner wall having an outside surface and an inside surface, an area surrounding an inlet, an area surrounding an outlet, and an area surrounding a fluid flow path, wherein the inner wall provides a fluid boundary and connects the inlet and the outlet. The method further including forming a portion of the inner wall that receives a valve seat, forming a portion of the inner wall that receives a control stem and a control element, and forming a lattice structure by depositing a solidifiable material onto the inner wall in a predetermined pattern, wherein the lattice structure is three-dimensional and includes a plurality of connected lattice members.

Abstract: A body of a fluid control apparatus includes an inlet, an outlet, and a fluid flow path connecting the inlet and the outlet. A first flange surrounds the inlet and a second flange surrounds the outlet. A bore is sized to receive a control stem and a control element. An inner wall includes an outside surface, an inside surface, an area surrounding the bore, an area sized to receive a valve seat, an area surrounding the inlet, an area surrounding the outlet, and an area defining the fluid flow path. A three-dimensional lattice structure is attached to the inner wall. The lattice structure includes a plurality of connected lattice members and is integrally formed with the inner wall.

Abstract: A cage for a fluid valve. The cage includes a first cage ring, a second cage ring, and a lattice structure disposed between the first cage ring and the second cage ring. The lattice structure defines a plurality of interconnected flow paths between an internal surface of the lattice structure and an external surface of the lattice structure. The lattice structure has a non-uniform density.

Abstract: An axial flow regulator includes a lateral access port through a portion of the valve body that provides access to a valve seat assembly and/or other portions of the valve trim without having to remove or uncouple the outlet flange or the inlet flange from the adjacent pipe sections. The lateral access port may extend through an outlet flange portion of the valve body and is configured to allow a valve seat assembly to be laterally inserted into and removed from the outlet flange. A valve seat assembly which may be configured for installation in the axial flow regulator includes a pad holder and a support ring for the pad holder that is separable from the pad holder. The pad holder may have alignment struts projecting radially outwardly from a pad support body. The support ring may include strut receivers that slidably receive the alignment struts of the pad holder.
