DEPT OF DEFENSE.DEPT OF THE NAVY.NAVSUP.NAVSUP WEAPON SYSTEMS SUPPORT.NAVSUP WSS MECHANICSBURG.NAVSUP WEAPON SYSTEMS SUPPORT MECH · Response deadline: Mon, 23 Nov 2026
What the government is buying
The Department of the Navy is soliciting bids for a throttle valve through NAVSUP Weapon Systems Support Mechanicsburg. This falls under federal supply classification 4820, which covers valves and related hardware used in fluid control systems. Throttle valves specifically regulate flow rates in piping systems by adjusting the cross-sectional opening, making them critical components in shipboard mechanical systems, propulsion plants, and other naval applications where precise flow control is required.
NAICS 332919 covers other metal valve and pipe fitting manufacturing, a sector that produces industrial valves from various metals for fluid power transmission, plumbing, heating, and manufacturing uses. Defense valve procurement typically demands adherence to stringent military specifications (MIL-SPEC) for performance, materials traceability, and reliability under demanding operational conditions including corrosion resistance, pressure cycling, and extended service life.

Who can bid
This solicitation is open to all responsible bidders—no small-business set-aside applies. Any manufacturer or distributor capable of meeting the Navy's technical and contractual requirements may submit an offer. Small businesses remain eligible and competitive, particularly those with:
- Experience producing valves to military or marine specifications
- ISO 9001 or AS9100 quality certifications
- Existing Defense Logistics Agency (DLA) or Navy supply arrangements
- Capacity for First Article Testing if required
Contractors should verify their sam.gov registration is active, their NAICS 332919 size standard eligibility is documented, and any required cybersecurity (NIST 800-171) or supply-chain risk management representations are current.
How to put together a competitive bid
Valve solicitations for military applications emphasize technical compliance over low price alone. Focus your proposal on:
Specification precision: Obtain the full technical package from SAM.gov. Identify whether the throttle valve must meet a specific MIL-SPEC (e.g., MIL-V-24624), commercial item description, or unique performance specification. Document your exact conformance point-by-point.
Material and process documentation: Naval applications require full material traceability, certified test reports, and often domestic sourcing under the Buy American Act or specialty metals restrictions. Prepare mill certifications, heat treatment records, and testing protocols in advance.
Quality assurance: Describe inspection procedures, pressure testing methodologies, and acceptance criteria. Reference past defense contracts or marine valve production as evidence of capability.
Delivery and packaging: See the solicitation for required markings, preservation methods, and shipping instructions. Defense supply chains have strict packaging standards (MIL-STD-2073).
Pricing structure: Itemize unit price, any required spares, and tooling costs separately. Note whether the Navy seeks a one-time buy or multi-year indefinite delivery arrangement.
