The Department of Defense, specifically the Department of the Navy through NAVSUP Weapon Systems Support MECH, is seeking to procure a valve assembly identified by NSN 7H-4820-010904455. The procurement involves a quantity of four units, with delivery terms set to FOB Origin, and is intended to be negotiated with a single source due to the lack of available data or rights for alternative sourcing, as determined under FAR 6.302-1. These valves are critical components in various defense applications, and the government has indicated that it is uneconomical to reverse engineer or purchase the necessary data for competitive procurement. Interested parties are encouraged to express their interest and capabilities within 45 days of this notice, with all proposals considered at the government's discretion. For further inquiries, contact Robert Langel at (717) 605-3353 or via email at ROBERT.H.LANGEL.CIV@US.NAVY.MIL.
