The Department of Defense, specifically the Department of the Navy, is seeking to procure 11 Flow Control Valves under a sole source contract with Portland Valve. The requirement includes the acquisition of valves identified by part number 506-4010 and NSN 4810 015213728, with delivery terms set to FOB Origin. These valves are critical components used in various defense applications, and the government has determined that it is uneconomical to obtain the necessary data or rights to source them from alternative suppliers. Interested parties are encouraged to contact Cody Smith at NAVSUP Weapon Systems Support for further information, with proposals due within 45 days of the notice publication. The procurement will be conducted under FAR 6.302-1, indicating a non-competitive process.
