The Department of Defense, through the Defense Logistics Agency, is seeking to procure 12 units of a linear valve and other replacement parts, specifically identified by NSN 7H-4810-012284228. The procurement is intended to be negotiated with Sargent Aerospace & Defense, LLC, as the sole source, due to the government's determination that acquiring data rights or reverse engineering the part is uneconomical. These valves are critical components in various defense applications, and the government is not soliciting competitive proposals at this time; however, interested parties may express their capability to meet the requirement within 45 days of this notice. For further inquiries, interested vendors can contact Jennifer Elliott at jennifer.elliott@dla.mil.
