DEPT OF DEFENSE.DEPT OF THE NAVY.NAVSUP.NAVSUP WEAPON SYSTEMS SUPPORT.NAVSUP WSS PHILADELPHIA.NAVSUP WEAPON SYSTEMS SUPPORT · Response deadline: Mon, 16 Nov 2026

What the government is buying

The U.S. Navy, through NAVSUP Weapon Systems Support Philadelphia, is soliciting offers for a valve assembly, specifically for repair or modification work. This falls under Federal Supply Classification 4810—Valves, Powered—which covers various types of valves and valve-related components used in mechanical systems.

NAICS code 332919 covers "Other Metal Valve and Pipe Fitting Manufacturing," though in this case the work involves repair and modification rather than new production. Valve repair and modification contracts typically require specialized technical capabilities, including disassembly, inspection, reconditioning, replacement of worn components, testing to original specifications, and documentation of work performed. The military's valve systems often operate in demanding environments aboard ships or aircraft, so adherence to precise technical standards is essential.

How to put together a competitive bid

Technical capability: Demonstrate your facility's capacity for precision machining, welding, non-destructive testing, and pressure testing. NAVSUP WSS typically requires detailed repair procedures and test reports.

Quality assurance: Present your quality management system certifications, inspection procedures, and material traceability protocols. Source inspection by Navy representatives is common for this work type.

Past performance: Cite contracts for similar valve, pump, or fluid system component repairs. Include Defense Priorities and Allocations System (DPAS) experience if applicable.

Pricing strategy: Understand that repair contracts may be fixed-price with economic price adjustment or based on actual hours and materials. Review the solicitation's line-item structure carefully—NAVSUP contracts often use Government-Furnished Equipment (GFE) or require breakout of labor, materials, and overhead.

Delivery schedule: Shipyard and fleet maintenance schedules drive strict delivery requirements. Confirm your capacity to meet required delivery dates before committing.
