What the government is buying
The Department of the Navy is soliciting offers for check valves through NAVSUP Weapon Systems Support Mechanicsburg. Check valves are mechanical devices that allow fluid to flow in one direction only, preventing backflow in piping systems. These components are widely used in naval vessels and shore facilities for fuel, water, steam, and hydraulic systems to protect pumps, compressors, and other equipment from damage caused by reverse flow.
NAICS 332919 covers "Other Metal Valve and Pipe Fitting Manufacturing," which includes manufacturers of industrial valves made from metal. This classification applies to businesses that produce valves for various applications, including military and maritime uses where durability and reliability under demanding conditions are critical.

Who can bid
This solicitation is set aside for no one—it is a full and open competition. Any responsible offeror, regardless of business size or socioeconomic status, may submit a bid. This includes large manufacturers, small businesses, and nontraditional defense contractors.
Small businesses in NAICS 332919 with capabilities in metal valve manufacturing should evaluate whether they can meet any applicable technical, quality, and delivery requirements. Firms without prior Navy contracting experience should pay particular attention to any Defense Federal Acquisition Regulation Supplement (DFARS) clauses and military specifications that may apply to marine-duty valves.
How to put together a competitive bid
Understand the technical requirements thoroughly. Check valves for Navy use must typically meet stringent military specifications for material composition, pressure ratings, corrosion resistance, and dimensional tolerances. Review the solicitation for specific standards such as MIL-V, ASTM, or ASME codes that apply.
Assess your manufacturing capacity and certifications. Naval valve contracts often require quality systems meeting ISO 9001 or NADCAP accreditation for special processes like welding or nondestructive testing. Verify your current certifications align with solicitation requirements.
Price competitively but sustainably. Full and open competition against established defense contractors means pricing pressure will be significant. Factor in costs for first article inspection, testing, and any required Navy qualification processes.
Evaluate your supply chain. Source materials early—naval-grade alloys and castings may carry long lead times. Document traceability requirements for materials, as DoD contracts typically mandate complete lot tracking.
Prepare for inspection and acceptance. Government representatives may require source inspection at your facility before shipment. Understand the acceptance criteria and any required test reports or certificates of conformance.
Address past performance and experience. Even without size restrictions, the Navy evaluates technical capability and delivery history. Highlight relevant marine, shipbuilding, or military valve contracts in your proposal.
