The Department of Defense, specifically the Department of the Navy through NAVSUP Weapon Systems Support MECH, is seeking to procure five units of a linear direct valve, identified by NSN 7H-4810-014334443. This procurement is based on a presolicitation notice indicating that the government intends to negotiate with only one source due to the unavailability of data or rights necessary for competitive procurement, making it uneconomical to reverse engineer the part. The selected supplier will be responsible for delivering the specified quantity under FOB origin terms, with proposals being accepted for 45 days from the notice publication date. Interested parties can reach out to Robert Langel at (717) 605-3353 or via email at ROBERT.H.LANGEL.CIV@US.NAVY.MIL for further information.
