This is a Statement of Work (SOW) for the manufacturing and machining of high-pressure industrial water valve parts for NASA's A1 test stand located at Stennis Space Center, Mississippi.

The vendor is required to cast seven (7) 6-inch 150 lb flange valve main bodies and machine them per drawing LM-7778, and cast seven (7) 6-inch 150 lb flange valve end housings per drawing LM-7776. The molds will be provided by NASA and must be returned upon project completion. All valve components shall be manufactured from CF8 stainless steel conforming to ASTM A351 standards. Casting tolerances must comply with ISO 8062-4:2017 Grade P and S General Tolerance 10, while machined tolerances are specified in a provided table with ranges from ±1/16" for fractional dimensions to ±.010" for three decimal place dimensions. Inspection shall follow MSS-SP-55 requirements, and all valves must pass pressure testing at 350 psi and may be subject to non-destructive examination (NDE) testing by NASA for cracks and voids. The estimated lead time for completion is 12 weeks, with delivery to building B-4120 at Stennis Space Center, MS 39529. The point of contact is Ryan Seals.
