What the government is buying

The Naval Supply Systems Command (NAVSUP) Weapons Systems Support is soliciting bids for repair and modification work on a valve disk assembly. This falls under federal supply classification 4820, which covers valves and related fluid control equipment. The specific item is a mechanical component used in valve systems, likely for naval vessels or support equipment given the NAVSUP WSS customer base.

NAICS code 332919 designates "Other Metal Valve and Pipe Fitting Manufacturing," a classification that includes repair and modification services for industrial valves. NAVSUP WSS Mechanicsburg serves as the primary procurement organization for Navy weapons systems support, managing spare parts and repair programs for naval aviation and maritime platforms.

Key facts

Who can bid

With no set-aside program specified, this appears to be a full and open competition under standard federal contracting rules. Any responsible source may bid, including large businesses and small businesses. However, small businesses registered under NAICS 332919 should verify their size standard for this code, as eligibility for future Navy small business programs depends on maintaining appropriate size certifications in SAM.gov.

Contractors in the valve repair and modification sector should confirm their capabilities align with any technical requirements—including material specifications, testing protocols, and quality assurance standards typical of Navy maritime equipment. Past performance with Department of Defense valve repairs, MIL-SPEC compliance experience, and active facility clearances may strengthen a bidder's position.

How to put together a competitive bid

For valve repair and modification solicitations, competitive bids typically emphasize technical compliance and traceability. NAVSUP WSS procurements often require detailed repair procedures, source inspection acceptance, and documentation of replacement materials.

Bidders should prepare: detailed technical proposals showing understanding of valve disk assembly function; proposed repair methodology with any deviations clearly flagged; evidence of relevant NFPA, ASME, or military specification compliance; and quality control plans with inspection points. If the solicitation includes deliverables beyond physical repair—such as data rights, engineering change proposals, or depot-level maintenance—address these explicitly.

Pricing should account for uncertain material conditions common in repair work. Consider whether to propose firm-fixed-price, cost-plus, or economic price adjustment terms if the scope allows flexibility. NAVSUP WSS frequently evaluates on lowest price technically acceptable criteria for routine repair work, making cost realism essential.

Review any specific clauses related to counterfeit parts prevention, DFARS specialty metals restrictions, and Navy unique identification requirements that commonly attach to shipboard component procurements.
