The Department of Defense, specifically the Department of the Navy through NAVSUP Weapon Systems Support, is seeking to procure eight electro-hydraulic valves for repair or modification. This procurement is classified under the PSC code 1710, which pertains to aircraft landing equipment, and is intended for a sole source negotiation due to the critical nature of the item and the lack of available technical data for alternative sources. The selected supplier must be an approved source as the item is flight critical, and interested parties are encouraged to submit their interest and capability to respond to this requirement. For further inquiries, Alexis K. Healy can be contacted at (215) 697-1143 or via email at ALEXIS.HEALY@NAVY.MIL, with the expectation that responses will be considered prior to the award date.
