What the government is buying
The U.S. Navy is soliciting bids for a check valve, a mechanical device that allows fluid to flow in one direction and prevents backflow. Check valves are critical components in naval systems including piping networks, propulsion systems, and various fluid handling applications aboard ships and submarines. The specific technical requirements—size, material, pressure rating, end connections, and applicable military specifications—see the solicitation.
This procurement is being handled by NAVSUP Weapon Systems Support Mechanicsburg, the Navy's primary inventory control point for weapons systems support, which manages spare parts and supply chain operations for naval aviation and maritime programs.

Who can bid
This solicitation is full and open competition with no set-aside, meaning all responsible sources—including large businesses, small businesses, and non-traditional defense contractors—may submit offers. NAICS 332919 covers manufacturers of metal valves and pipe fittings not classified elsewhere, including industrial check valves, control valves, and pressure relief valves.
To compete, your firm must be capable of manufacturing or supplying valves meeting the Navy's technical and quality requirements. For manufacturers, this typically means holding appropriate ISO certifications, experience with military specifications (such as MIL-V or MIL-STD), and capacity for material traceability and testing documentation. Distributors may also bid if the solicitation permits non-manufacturer sources.
Register in SAM.gov and hold valid Cage Code and NACS registration to contract with DoD. If you are a small business, ensure your size standard for NAICS 332919 (1,000 employees) is current in your SAM profile, as this affects future subcontracting opportunities even though this specific procurement has no small-business preference.
How to put together a competitive bid
Understand the technical requirements. Check valves for naval applications often must meet stringent material standards (bronze, stainless steel, or naval brass depending on service fluid), pressure-temperature ratings, and military or commercial equivalent specifications. Obtain the full specifications referenced in the solicitation—likely drawing numbers, MIL-Specs, or technical data packages—and confirm your product qualifies or identify the cost to qualify it.
Address quality assurance. NAVSUP WSS typically requires suppliers to maintain quality systems meeting ISO 9001 or equivalent, with specific documentation for material certifications, hydrostatic testing, and non-destructive examination. Prepare to submit a quality assurance plan and evidence of past performance with similar critical applications.
Price competitively for aftermarket spares. NAVSUP Mechanicsburg procurements often support legacy weapon systems with long lifecycles; the government balances unit price against total life-cycle cost, reliability, and delivery performance. Research historical pricing for similar NSN items if available. Consider offering multi-year pricing or volume discounts if the structure permits.
Review packaging and marking requirements. Defense supply chain requirements include MIL-STD-129 marking, RFID compliance, and specific preservation packaging for corrosion-prone metal components. Factor these costs into your price and production schedule.
Assess delivery and logistics. The solicitation may require delivery to a specific Defense Logistics Agency depot or direct to fleet units. Understand freight terms, required delivery date, and whether Just-in-Time delivery or inventory stocking is expected.
