This is a total small business set-aside contract for manufacturing a parts kit for a crucial shipboard ball valve system, designated as SPECIAL EMPHASIS material due to the high risk of personnel injury or loss of ship if defective. The contractor must manufacture a ball and two seats per specific Navy drawings, using SAE-AMS-6931 for the ball and a specialized cast nylon for the seats, with the ball requiring an Alumina-Titania/PTFE coating per a proprietary procedure. The work involves strict quality assurance, including a mandatory ISO-9001 quality system, extensive testing certifications (hydrostatic, dye penetrant, weld procedures), and configuration control with government approval required for any waivers or engineering changes. Performance of services is subject to government quality assurance at the contractor's source location, which cannot be changed without authorization. No budget amount or submission timelines are specified in the description.
