About this opportunity
NASA Stennis Space Center, through the NASA Shared Services Center as contracting activity, has awarded contract 80SSC026P00001 to Gosco Valves on a sole-source basis for fabrication, assembly, LOX cleaning, functional testing, packaging, and documentation of two multi-stage liquid oxygen pressure control valves.
The justification cites 10 U.S.C. 3204(a)(1), asserting that Gosco Valves is the only responsible source capable of providing the specific two-stage dual-ball LOX valve design meeting NASA's safety, compatibility, and performance requirements for throttling high-flow liquid oxygen at pressures typical in ground-based rocket propulsion component-level testing. The valve's proprietary internal sealing, ball-rotation, and throttling characteristics are uniquely required for integration with the E-1 Test Stand's system controls and actuator interfaces. Market research conducted through NASA technical personnel, industry surveys, and procurement history found no alternative vendors producing functionally equivalent dual-ball assemblies or comparable ignition mitigation features. A SAM.gov synopsis published March 16–31, 2026 yielded no industry responses. Deliverables include fully assembled, cleaned, and bagged valves accompanied by drawings, test reports, material certifications, cleaning certificates, and maintenance tools or soft-goods kits as required. The estimated delivery timeframe is 32 weeks. NASA estimates that substituting an alternative valve supplier would require system reanalysis, oxygen compatibility retesting, and requalification with projected costs of $250,000 to $500,000 and schedule delays exceeding one year. Place of performance is Stennis Space Center.
