16--VALVE,ECS
DEPT OF DEFENSE.DEPT OF THE NAVY.NAVSUP.NAVSUP WEAPON SYSTEMS SUPPORT.NAVSUP WSS PHILADELPHIA.NAVSUP WEAPON SYSTEMS SUPPORT · Response deadline: Fri, 27 Nov 2026
What the government is buying
The Department of the Navy, specifically NAVSUP Weapon Systems Support Philadelphia, is soliciting bids for a valve related to Environmental Control Systems (ECS). This falls under aircraft parts and equipment procurement, as ECS valves are critical components that regulate cabin pressure, temperature, and airflow in military aircraft.
NAICS code 336413 corresponds to "Other Aircraft Parts and Auxiliary Equipment Manufacturing." This classification covers manufacturers and suppliers of specialized aircraft components that don't fall under complete airframe or engine production. ECS valves require precision engineering, aerospace-grade materials, and compliance with stringent military specifications for reliability in demanding flight conditions.
Without additional details in the metadata, the specific valve type, platform compatibility, and technical requirements are not available—see the solicitation.

Who can bid
This solicitation is open to all qualified businesses—no small business set-aside applies. Large enterprises, small businesses of any size, and non-traditional defense contractors may compete.
To be competitive, bidders should:
- Be registered in SAM.gov with active status
- Hold valid CAGE code
- Demonstrate experience with aerospace or military-grade valve manufacturing
- Maintain AS9100 or equivalent quality management certification (standard for aerospace suppliers)
- Possess or be able to obtain necessary security clearances if the platform is classified
Small businesses without defense contracting experience face higher barriers here. The lack of set-aside means you'll compete directly with established defense primes and Tier-1 suppliers. Consider subcontracting relationships or joint ventures if you lack direct manufacturing capacity or past performance with NAVSUP WSS.
Veteran-owned, woman-owned, or HUBZone small businesses may still pursue this, but without set-aside protection, price and technical capability drive award decisions.
How to put together a competitive bid
Technical volume: NAVSUP Weapon Systems Support typically requires detailed specifications adherence. Emphasize manufactured traceability, material certifications, and testing protocols. Include production capacity and lead time commitments—naval aviation readiness depends on reliable supply.
Past performance: Document directly relevant valve or ECS component deliveries, especially to DoD or commercial aviation. Navy evaluators weight recent, similar contract performance heavily.
Pricing: Open competition invites aggressive pricing. Analyze your total cost basis including specialized tooling, testing, and quality assurance. Consider long-term production potential when pricing initial orders.
Quality certifications: Obtain and highlight AS9100D certification and any NADCAP special process approvals. Military aerospace procurement rarely waives these requirements.
Proposal compliance: Follow solicitation instructions exactly. NAVSUP WSS Philadelphia evaluates strict adherence to submittal requirements; non-compliant proposals face quick elimination regardless of technical merit.
