A -- MINIATURIZED LATCHING SOLENOID VALVES POC Mary Petkoff, Contracting Officer, Phone (301)286-6143, Fax (301)286-1739, Email Mary.J.Petkoff.1@gsfc.nasa.gov WEB: Click here for the latest information about this notice, http://procurement.nasa.gov/EPS/GSFC/date.html#915-60995A. E-MAIL: Mary Petkoff, Mary.J.Petkoff.1@gsfc.nasa.gov. NASA/GSFC plans to issue a sole source modification to contract NAS5-31332 with Aker Industries to increase the quantitiy of miniaturized solenoid latching valves by 30 standard valves and 10 rupture disk valves. The additional valves are for the upcoming Cassini mission, and are expected to be delivered four months after the execution of the modification. Aker Industries developed valves which included the following characteristics: construction mainly of titanium to allow for a weight of 27 grams, dimensions of .5" diameter x 1.25" long, latching solenoid type, actuator assembly sealed off from the gas flow by means of a bellow assembly to minimize contamination into the gas stream from outside sources, and the capability for the valves to attach to the instruments manifold by way of a leak tight 'C' seals. The leak rate across the valve seat shall be less than 6E-10 atm.cc/sec for helium at room temperature. The leak rate from outside the valve housing into the gas sampling region (case leakage) shall be less than 4E-10 atm.cc/sec from helium at room temperature. In addition, the valves should successfully operate within specifications during a minimum of twelve 300 degree C, 24 hour bakeout cyles. NASA/GSFC intends to purchase the items from Aker Industries. The RFP that resulted in the award of contract NAS5-31332 was issued competitively; however, Aker Industries was the only company to respond. The statutory authority for Other Than Full and Open Competition is 10 U.S.C. 2304(C)(1) -- Only One Responsible Source. See Numbered Note 22 and 26. Interested firms have 15 days from publication in the Commerce Business Daily (CBD) to submit their qualifications/capabilities. Such qualifications/capabilities will be used solely for the purpose of determining whether or not to conduct this procurement on a competitive basis. Responses received after 15 days without the required information will be considered nonresponsive to the synopsis and will not be considered. A determination by the Government not tocompete this proposed contract modification, on a full and open competitive basis, based upon responses to this notice, is solely within the discretion of the Government.
