Answer: Number 13, part number 82D38-3, tech order 15A2-2-179-3 should not be in Appendix D and is not a requirement for this SOW. Everything else is relevant.
2. What is the manufacture, part number of the vacuum pumps.
Answer: This information is not avaliable at this time. Once the information is avaliable, the government will provide.
3. Please provide available nameplate information such as manufacturer, part number, serial number for each valve listed in section 3.2.23 for replacement.
Answer: Reference Section 3.2.23.
| The 16 inch (CSV_1 and CSV_2) valves are Crane Company part number 468509 | |
| The 12 inch (VCV_1 and VCV_2), 4 inch (BV_1 and BV_2), 3 inch (BV3_1 and BV3_2), 10 inch PCV_1 are all Philadelphia Gear Works "Limitorque" valves.
