The Department of the Navy Naval Supply Systems Command is seeking quotations for eight disk valve assemblies (NSN 1HM 4820-01-418-0871 C1), critical Level One oxygen-clean valve components for shipboard systems where material failure could result in loss of life or vital equipment failure. This is a sole-source procurement designated as a Level 1 requirement from VACCO Industries, as the Government does not own the technical data or rights necessary to source this part from alternative suppliers and has determined it uneconomical to acquire such data or reverse engineer the component. The procurement is rated DO under the Defense Priorities and Allocation System, indicating high-priority acquisition status. Contractors must comply with extensive technical specifications including oxygen cleaning per MIL-STD-1330, Level I Source Certification, material traceability requirements, and quality assurance standards per ISO-9001, with all objective quality evidence submitted via WAWF to Portsmouth Naval Shipyard for review and acceptance. The evaluation will prioritize past performance as the more important factor relative to pricing, and quotations must be received by May 15, 2026.

This procurement carries no set-aside designations and identifies VACCO Industries as the sole-source incumbent contractor. The contract requires a 200-day delivery timeline from award, with performance to be completed in the United States. While no specific award value is disclosed in the solicitation notice, the procurement specifies a quantity of eight valve disk assemblies. The solicitation mandates compliance with numerous FAR and DFARS clauses covering Buy American provisions, cybersecurity safeguards, hazardous material identification, and conflict minerals requirements, establishing a comprehensive regulatory framework for contract performance and delivery of these critical naval components.
