Navy NAVSUP WSS seeks a flange-mounted valve assembly stem manufactured to Marotta Scientific Controls drawing 195461-0001; the item is Special Emphasis/Level I material for a critical shipboard system with extensive quality, traceability, testing, welding, and certification requirements. The requirement includes NIIN 014068542 at quantity 3 and increases NIIN 014071381 from 3 to 7 units, with award issued bilaterally requiring contractor written acceptance under Emergency Acquisition Flexibilities and a DPAS rating for national defense. If the offeror is not the OEM, it must identify the OEM name/CAGE and provide a signed OEM distributor authorization letter; if packaging occurs at another location, it must provide that facility’s name, address, and CAGE.
