Abstract: Features for a valve assembly are described. The features can include a pair of spaced walls having apertures defining non-linear exit flow paths for the fluid, such as air, exiting the valve. In some embodiments, the features are described for a bleed valve assembly, to reduce the decibels produced when used in high pressure contexts, such as aircraft engines. The noise suppression features are integrated with the valve assembly. A valve, such as a stem and valve head, can move within the assembly between open and closed positions. The valve assembly can be manufactured using additive layer manufacturing (ALM) to create a monolithic housing that in some embodiments has the noise suppression features built into the assembly.
