Abstract
A baffle insert or sleeve is disclosed for the integration of the downstream pressure tap into a pressure regulation valve ('PRY') for an aircraft environmental control system ('ECS'). The purpose of this insert is to return the flow, disturbed by the pivoting disk of a butterfly valve, to a more normal distribution within the length of the valve body. This allows the PRV downstream pressure tap to be part of the valve, instead of it (along with additional plumbing) being located four more pipe diameters beyond the valve housing.
