E-MAIL: Wendy L. Boudreaux, wendy.l.boudreaux1@jsc.nasa.gov. NASA/JSC plans to issue a Request for Proposal (RFP) for the design, development, fabrication, qualification and delivery of 20 pyrotechnic isolation valves. The valve will be used in space suited crew member self rescue emergency equipment and the requirements are very stringent. Preference shall be given to valve designs which preclude introducing contamination into the downstream flow path and have demonstrated flight worthiness and high reliability. The valve shall be a normally closed, interference fit design, have a maximum design pressure (MDP) of 10,000 psig at 144 degrees farenheit with a proof rating of 15,000 psig and a minimum burst of 25,000 psig. The maximum envelope and external configuration is specified by drawing SLG 33110980 which can be requested by fax at (281) 244-5331. The body shall be 2.4 inches in length, maximum, excluding the initiator. The inlet and outlet ports shall be at 90 degrees, and offset 0.250 inches. The ports shall be in accordance with MS33649-04. The outlet flow port area shall be equivalent to a 0.039 inch diameter orifice with a discharge coefficient (Cd) of 0.8. The operational storage life shall be 10 years minimum. The operating environment shall be -20 to +144 degrees farenheit. The valve shall be actuated by a Government furnished NASA Standard Initiator (NSI). The valve shall be delivered cleaned to level 100 A in accordance with MIL-STD-124C. The leak rate shall be less than 1x10 to the -6 standard cubic centimeters per second (sccs) GHe at MDP. Propellant gases or particulates vented into the pyrovalve flowstream during firing shall maintain the requirements of level 100 in accordance with MIL-STD-1246C. This requirement shall be demonstrated as a part of development testing on three flight like units and the contractor shall participate in a Development Test Results Review (DTRR). Twenty valves shall be delivered no later than 8/31/99. Fluid media will be nitrogen, air, helium, water, and freon 14. Qualification testing shall include the testing in the matrix that can be requested by fax at (281) 244-5331 and the contractor shall participate in a Qualification Test Results Review (QTRR) and present the final qualification report. The contractor shall perform Acceptance Testing on each valve in accordance with the approved Test Plan. These valves shall be shown to be a leak before burst design. The supplier shall conduct tensile tests on standard tensile bars (coupons) in accordance with AMS 5643 from the same lot as the valve body material. Qualification testing specifications can be requested by fax at (281) 244-5331. The Government intends to acquire a commercial item using FAR Part 12. The SIC Code and Size Standard are 3769 and 1000, respectively. The DPAS Rating for this procurement is DO-C9. The provisions and clauses in the RFP and model contract are those in effect through FAC 97-04. All qualified responsible sources may submit an offer which shall be considered by the agency. The anticipated release date of the RFP is on or about 6/30/98 with an anticipated offer due date of on or about 7/31/98. An ombudsman has been appointed -- See Internet Note "B". The solicitation and any documents related to this procurement will be available over the Internet. These documents will be in Microsoft Office Suite (Word 6.0, Excel 5.0, PowerPoint 4.0) format and will reside on a World Wide Web (WWW) server, which may be accessed using a WWW browser application.
