The Department of Defense, specifically the Department of the Navy through NAVSUP Weapon Systems Support MECH, is seeking to procure six units of a linear direct valve, identified by NSN 7H-4810-011769748. The procurement is based on a presolicitation notice indicating that the government intends to negotiate with only one source due to the lack of available data or rights for alternative procurement methods, making it uneconomical to reverse engineer the part. This valve is crucial for military applications, and the delivery will be on a FOB origin basis. Interested parties are encouraged to express their interest and capability within 45 days of the notice, with the primary contact being Kaitlyn Mounts at kaitlyn.t.mounts.civ@us.navy.mil for further inquiries.
