What the government is buying
The Navy is soliciting bids for a valve assembly, environmental—a component used in naval weapons systems. This procurement is being handled by NAVSUP Weapon Systems Support (WSS) in Philadelphia, the organization within NAVSUP that provides logistics and sustainment support for Navy and Marine Corps weapons systems.
NAICS code 336413 classifies this as Other Aircraft Parts and Auxiliary Equipment Manufacturing. While this code broadly covers aircraft components, it also applies to specialized fluid control systems and valve assemblies used in military applications. Environmental valve assemblies typically regulate or isolate fluid flow in systems where protecting equipment from external conditions—such as seawater, pressure changes, or contamination—is critical. These components are essential for maintaining operational readiness of naval platforms.

Who can bid
This solicitation is open to all responsible sources—no small-business set-aside applies. Any qualified business, regardless of size, may compete. However, small businesses registered in SAM.gov with active 336413 NAICS code representations should still consider bidding, as they may qualify for subcontracting opportunities or future set-aside work with NAVSUP WSS.
To bid, your firm must:
- Be registered in SAM.gov with active registration covering the solicitation period
- Have the 336413 NAICS code in your profile
- Meet any facility clearances, quality certifications, or defense contractor requirements specified in the full solicitation (common for naval aviation/aerospace components)
Specialized valve assemblies for military weapons systems often require ISO 9001 or AS9100 quality management certification, DFARS compliance, and potentially ITAR registration depending on technical specifications. See the solicitation for exact requirements.
How to put together a competitive bid
For manufacturing-type solicitations at NAVSUP WSS Philadelphia:
Examine the drawing package and technical data carefully. NAVSUP WSS Philadelphia manages spare and repair parts for legacy and current weapons systems; specifications may reference military standards (MIL-STD, MIL-PRF, or MS/AN/NA part numbers) that govern materials, tolerances, and testing protocols.
Verify your supply chain for specialty materials or coatings. Environmental valve assemblies may require corrosion-resistant alloys, seals rated for operational environments, or specific platings. Solicitation drawings will identify approved sources or equivalence requirements.
Assess past performance weighting. NAVSUP WSS evaluations typically consider delivery history, quality metrics (reject rates, corrective action responses), and adherence to technical requirements. Emphasize relevant contract history with DLA, NAVSUP, or aerospace OEMs.
Price strategically for the full contract ceiling. Without a set-aside, competition may include large defense contractors. Small businesses should evaluate whether their cost structure, specialized capabilities, or OTTO (Other Than Traditional) manufacturing approaches offer differentiation.
Confirm packaging and marking requirements. Defense Logistics Agency (DLA)-managed items frequently have specific military packaging specifications that affect quoted costs.
