MEMORANDUM FOR AFSC/PZIMA

FROM: 76 CMXG/ENA

SUBJECT: Brand Name Justification for Test Cell Control Valve Rebuild Components

1. 76 CMXG/ENA is requesting a contract to procure Test Cell Control Valve Rebuild

Components. The Test Cell Control Valves are utilized in the high pressure and high temperature process piping and control systems in the 16 Pneumatic Test Cells at the Air Driven Accessories Overhaul and Test Facility.

2. These test cell control valves work in conjunction with the a process piping system to provide controlled high volume high pressure high temperature process air to simulate jet engine operating conditions to performance test depot overhauled regulating valves, anti-icing valves, cooling turbines, and other cabin environmental control components used on most all aircraft in the Air Force inventory. The B-1, B-52, C-5, C-130, KC-135, E-3A, F-15, and F- 16 are the primary weapon systems supported by this air compressor. The loss of any of these control valves is a critical problem because our testing capacity will reduced. This will result in limited functional test capability for the Pneumatic Test Cells in the Air Driven Accessories Overhaul and Test Facility and could result in mission impaired capability awaiting parts (MICAP) for these weapon systems.

3. Valtek Mark IX Deltastream Rebuild Components are the only know components that can be utilized in the repair of the existing control valves. In Accordance with FAR Part 6.302- 1(c)(1) these brand name items arerequired. Flowserve is the original equipment manufacturer of the existing Valtek Mark IX Deltastream control valves and has proprietary data on materials and construction. Valtek Mark IX Deltastream rebuild components from Flowserve are the only know replacement parts that can be utilized to maintain the current form, fit, and function in the existing control valves without intensive and expensive studies.
