This is a total small business set-aside Navy procurement for a Compartment Salvage Ball Valve designated as SPECIAL EMPHASIS material for a crucial shipboard system, with a DO national defense priority rating under the Defense Priorities and Allocations System. The contractor must comply with extensive technical requirements, including material certifications, specified testing (liquid penetrant, ultrasonic, pressure), thread forming and inspection rules, Teflon coating specifications, welding restrictions, and configuration control with a formal waiver/deviation and engineering change process. A one-year warranty from date of delivery applies, the award will require the contractor's written acceptance, and past performance will be considered in the evaluation. The performance location is not specified, but if the requirement is packaged at a facility different from the offeror’s address, the name, street address, and CAGE of that facility must be provided. Offerors should note that this requirement is being processed under Emergency Acquisition Flexibilities, and drawings must be requested via SAM.gov with an email to the point of contact.
