What the government is buying
The Navy is soliciting for a valve, butterfly—a fluid control component commonly used in piping systems to regulate or isolate flow. Butterfly valves are employed across naval vessels and shore facilities for seawater, fuel, hydraulic, and other fluid systems. The defense supply system frequently procures these as spare parts for ship maintenance and overhaul programs. The specific technical requirements, including size, material, pressure rating, and applicable military specifications, see the solicitation.

Who can bid
This solicitation is open to all responsible sources—there is no small-business set-aside, meaning large businesses may compete alongside small businesses. Firms in NAICS 332919, which covers manufacturers of industrial valves, pipe fittings, and related components, are the natural bidders. However, any qualified source meeting the technical and qualifications requirements may submit an offer.
Small manufacturers in this NAICS should note the 500-employee size standard typically applied by SBA for this industry. If your firm qualifies as small under this threshold, this contract could contribute to your revenue base and past performance record, even competing directly against larger valve manufacturers. Distributors or value-added resellers may also be eligible if the solicitation permits non-manufacturer provisions or supply of commercial items.
How to put together a competitive bid
For butterfly valve procurements through NAVSUP WSS, bidders should focus on these distinct elements:
Technical compliance is paramount. Defense valve procureances typically reference military specifications (MIL-SPECs), MIL-STD drawings, or NAVSEA technical standards. Obtain and verify you can meet the exact specification cited in the solicitation—substitutions without approved equals are frequently grounds for rejection.
Traceability and quality documentation. Navy supply systems require material certifications, chemical and physical test reports, and chain-of-custody documentation. Prepare your quality management system to produce compliant certificates of conformance and, if required, evidence of Nadcap or ISO 9001 certification.
Pricing structure. NAVSUP WSS solicitations for spare parts often use historical pricing data. Research prior awards for similar national stock numbers (NSNs) through USAspending.gov or FPDS to benchmark your pricing. Account for domestic sourcing requirements under the Buy American Act and Berry Amendment if applicable to materials.
Past performance. If your firm lacks direct Navy valve experience, highlight comparable deliveries to other defense agencies, commercial marine, or nuclear/power generation sectors with similarly stringent quality requirements.
Delivery and packaging. Defense shipments require specific packaging, marking, and documentation per MIL-STD-129 and MIL-STD-2073. Factor these costs into your proposal.
