C-5 Fluid Regulating Valve
NSN: 4820-00-185-1032
PN: 7720140-101
The C-5 fluid regulating valve was designed specifically for the C-5 Galaxy aircraft which is a military transport aircraft. This part is peculiar to and will only be used on the C-5 Aircraft. The valve, PN 7720140-101, consists of an aluminum alloy housing and cover, a rubber-coated Dacron fabric diaphragm assembly and a mounting bracket. No external controls are required to operate the valve as pressure from the two aircraft liquid nitrogen (LN2) feedlines are fed through the valve, actuating the diaphragm assembly if the pressures are unequal. The valve senses the differential pressure between the two aircraft liquid nitrogen (LN2) feedline pressures at the fuel tank heat exchanger in the fire suppression system (FSS), then selects and directs the higher pressure to the valve pressure limiter port. The higher pressure is then applied to the Pressure Limiter Valve which monitors the regulator outlet pressure on both the right and left fuel tank systems to prevent fuel tank over-pressurization The Fluid Regulating Valve should be repaired IAW with Air Force (AF) Technical Manual 13F7-19-3 and the attached drawings.
CAUTION:
This market survey is being conducted to identify potential sources that may possess the expertise, capabilities, and experience to meet the requirements for qualification and repair of the C-5 Fluid Regulating Valve for use on United States Air Force (USAF) aircraft. The level of security clearance and amount of foreign participation in this requirement has not been determined. Contractors/Institutions responding to this market research are placed on notice that participation in this survey may not ensure participation in future solicitations or contract awards. The government will not reimburse participants for any expenses associated with their participation in this survey.
INSTRUCTIONS:
1. The document(s) below contain a description of the C-5 Fluid Regulating Valve requirement and a Contractor Capability Survey. The Survey allows Contractors to provide their company’s capability.
2. If, after reviewing these documents, you desire to participate in the market research, you should provide documentation that supports your company’s capability in meeting these requirements. Failure to provide documentation may result in the government being unable to adequately assess your capabilities.
3. ATTENTION: SMALL BUSINESS RESPONDENTS who are interested in participation for this effort:
a. No set aside decision has been made; however, the Government will determine the final strategy after thorough analysis of the small business responses and other market research available, considering the demonstrated interest and capability. Please ensure that you provide a thorough response to each question. If your company does not currently possess the full capability required to fulfill the entire requirement, what teaming/partnership/joint venture/subcontracting arrangement do you have in place to fulfill the government needs? Providing evidence of this arrangement, e.g. emails, letter, etc. that demonstrates a united response to this SSS is highly encouraged but not required. The evidence should state the type of arrangement and the role each member will fulfill. If you are only interested in being a subcontractor to the future awardee, state the portion of the work that your organization has capability of fulfilling.
b. Identify any areas of work that your organization believes should be broken out exclusively for Small Business.
4. Both large and small businesses are encouraged to participate in this Market Research. Joint ventures or teaming arrangements are encouraged.
5. Questions relative to this market survey should be addressed to the Program Manager, Janet Butcher
(janet.butcher@us.af.mill), with CC to the Contract Specialist, Caiveon Thomas (Caiveon.Thomas@us.af.mil) and PCO, Karen Beckford (Karen.Beckford@us.af.mil)
