What the government is buying
The U.S. Department of the Navy, through NAVSUP Weapon Systems Support Mechanic, is soliciting offers for valve, safety relief components. This procurement falls under Federal Supply Classification (FSC) 4820, which covers valves and related hardware used in fluid-power and piping systems.
Safety relief valves are critical pressure-control devices that automatically release excess pressure from systems—protecting equipment, personnel, and infrastructure in naval vessels and shore facilities from over-pressurization hazards. These components are essential to maintaining operational readiness across Navy weapon systems and support equipment.
The Navy typically procures such items under its Continuous Maintenance, Repair, and Operations (MRO) supply model, where NAVSUP WSS manages inventory and distribution of spare and repair parts to fleet and shore activities. Safety relief valves must meet stringent military specifications and certification requirements given their life-safety function in pressurized systems.

Who can bid
This solicitation is full and open competition with no small business set-aside. All responsible sources, including large manufacturers and non-traditional defense contractors, may submit offers.
To compete, your firm should:
- Register in SAM.gov with active registration valid through the award period
- Possess valid DUNS/UEI and maintain acceptable Past Performance ratings
- Demonstrate capability to manufacture or supply valves meeting mil-spec requirements typical for FSC 4820 items
- Have or obtain any required quality certifications (commonly ISO 9001, NIST compliance, or NAVSEA-specific approvals)
- Be prepared to meet DFARS flow-down provisions and Navy unique contract clauses
NAICS 332919 encompasses establishments primarily engaged in manufacturing metal valves (except industrial valves), pipe fittings, and similar components. If your primary NAICS differs, you may still bid if your capabilities align.
How to put together a competitive bid
Understand the technical requirements precisely. Safety relief valves for Navy applications typically must conform to specific military standards (see the solicitation for exact specifications). Request drawings, material certifications, and testing requirements through the Q&A process if not included in the initial posting.
Emphasize traceability and quality documentation. Naval supply chains require rigorous lot tracking, material certifications, and pressure-testing documentation. Bid proposals should detail your quality assurance processes, testing capabilities, and certificate of conformance procedures.
Evaluate your supply chain for specialty materials. High-performance alloys or corrosion-resistant materials common in marine environments may have long lead times. Your bid pricing and delivery schedule must account for actual material availability.
Assess your production capacity against delivery requirements. NAVSUP WSS orders often involve sporadic demand with short turnaround requirements. Demonstrate either in-house manufacturing flexibility or reliable subcontractor agreements.
Price strategically for competitive evaluation. With no set-aside, you'll compete against established defense suppliers. Evaluate recent contract awards for comparable NSNs in SAM.gov's Contract Opportunities archive to benchmark pricing.
Address packaging and labeling requirements. Military Standard (MIL-STD) packaging and RFID-compliant labels are commonly required for NAVSUP shipments. Non-compliance risks rejection and payment delays.
