What the government is buying

The Naval Supply Systems Command (NAVSUP) Weapons Systems Support office in Mechanicsburg, Pennsylvania is soliciting bids for a STEM, FLUID VALVE. This is a component typically used in systems where controlled flow of liquids or gases is critical—common applications include shipboard machinery, propulsion systems, auxiliary equipment, and various weapon systems platforms.

NAICS code 332919 places this in "Other Metal Valve and Pipe Fitting Manufacturing," which covers industrial valves not classified elsewhere, including fluid control valves made from metal alloys suitable for demanding operational environments. The classification code 4820 in the Federal Supply Classification system corresponds to "Valves, Nonpowered," confirming this is a manual or actuated valve rather than a solenoid or powered valve type.

Fluid valves for Navy applications typically must meet stringent specifications for corrosion resistance, pressure ratings, leak-tight performance, and material traceability. Given NAVSUP WSS's role as the Navy's primary inventory control point for weapon systems material, this valve likely supports sustainment of existing platforms rather than new construction. See the solicitation for exact technical specifications, approved materials, and performance requirements.

Key facts

With no set-aside designation, this opportunity is open to all responsible sources including large businesses, small businesses, and non-traditional defense contractors.

Who can bid

Any qualified manufacturer or distributor may compete. Small businesses are eligible to bid but receive no competitive preference—you'll compete directly with established defense contractors and original equipment manufacturers.

To be competitive, you should have:

• Active SAM.gov registration (mandatory)
• Experience with defense-unique requirements: MIL-STD specifications, DFARS clauses, and item unique identification (IUID) if applicable
• Manufacturer capabilities for metal valve production, or established relationships with approved manufacturers
• Past performance delivering to NAVSUP or similar DLA/Naval supply chains

If you're a small manufacturer in NAICS 332919, evaluate whether your production capacity and quality certification level (ISO 9001, AS9100, or Navy-specific QMS requirements) match this demand. Distributors may bid if the solicitation permits不变卖 sources, but military valve procurements often restrict to original manufacturers or authorized sources.

How to put together a competitive bid

Pricing strategy: Without set-aside protection, price competitiveness is paramount. Research NAVSUP WSS historical pricing for similar valve national stock numbers (NSNs) through FPDS or GSA Aerospace reports. Account for scarce material surcharges—naval-grade alloys like Monel, Inconel, or CRES 316L carry volatility risk.

Technical compliance: Request the full specification package immediately upon accessing SAM.gov. Fluid valves for Navy use often reference military specifications (MIL-V, MIL-DTL, or SAE standards). Verify your product's exact configuration matches: end connection type, pressure class, temperature rating, actuation method, and materials of construction.

First Article/Test requirements: NAVSUP sustainment contracts may require first article inspection or material certification. Budget for destructive testing, dye penetrant inspection, or pressure testing if invoked. See the solicitation for quality assurance provisions.

Delivery and packaging: NAVSUP Mechanicsburg contracts typically require MIL-STD-129 labeling and RFID-compliant shipment to Defense Distribution Centers. Confirm your logistics capability or third-party logistics arrangement.

Past performance: If you lack direct NAVSUP experience, emphasize comparable valves delivered to Coast Guard, MARAD, or commercial marine sectors under equivalent technical standards.

Next steps

Read the full solicitation on SAM.gov by searching solicitation number N0010426QZB64. The notice was posted October 15, 2026, with responses due October 29, 2026 at 4:30 PM Eastern Time—a 14-day turnaround requiring immediate action to obtain specifications and assess feasibility.

Critical immediate tasks: Download the technical data package, verify your SAM registration expiration, and confirm your DUNS/UEI information matches SAM exactly. Contact the contracting officer identified in SAM.gov with specification interpretation questions early; late inquiries may not be answered before deadline.

Note that NAVSUP WSS solicitations for individual NSN items rarely allow post-deadline revisions—submit complete, compliant proposals by the deadline or risk automatic rejection.
