RECOMMENDATION AND DETERMINATION TO SOLICIT FROM ONE SOURCE

OR BRAND NAME

PICK ONE

Sole Source:

☒I recommend that NASA, NASA Shared Services Center negotiate with Robert E. Mason & Associates, Inc. only for 8-inch KTM 3-way ball valve assembly with Bettis actuator and Topworx switchbox. The total estimated cost of this effort is and the estimated period of performance or lead-time for delivery is July 2, 2027.

OR

Brand Name Justification:

☐I recommend that NASA, NASA Shared Services Center negotiate with only with vendors who can provide the subject brand name from Manufacture Name for Enter Supply or Service to be procured. The total estimated cost of this effort is Enter Dollar amount and the estimated period of performance or lead-time for delivery is Date.

This recommendation is for the acquisition of supplies or services determined to be reasonably available from only one source/only one manufacture. Competition is impractical for the following reasons (please answer the questions below):

1. What are the reasons for soliciting only the suggested source/suggested brand name? Please provide the unique characteristics of the items or services along with the supporting rationale and the market research performed to substantiate your reason for the suggested source/brand name.

The required 8-inch KTM 3-way ball valve assembly with Bettis actuator and Topworx switchbox is a direct replacement for an existing valve in the HP air leg of the 20” Mach 6 tunnel in Building 1247D at LaRC. The existing piping configuration is engineered specifically for the face-to-face dimensions, flange orientation, flow coefficients, and weight footprint of the KTM NB1HF 3-way L-Port valve. Furthermore, the facility's pneumatic control system and hazardous-location electrical instrumentation are wired and calibrated specifically for the Bettis G4016-SR4 actuator and Topworx DXP switchbox with GO switches. Technical personnel conducted a market research to identify potential sources capable of providing an 8-inch ASME 300 3-way L-Port stainless steel ball valve that fits the existing system envelope. Catalog reviews and vendor inquiries were conducted. While other manufacturers produce 3-way valves, none offer a drop-in replacement that matches the exact dimensional, actuation, and metallurgical (Duplex 329 stem / Stellite seat) specifications required to interface with the existing LaRC system without major facility rework. Robert E. Mason & Associates provided Proposal No. CMR26-D7897 in the amount of

2. What is the impact to the government if another vendor/brand is used? Include any dollar, schedule, or compatibility impacts if possible.

Procuring an alternative valve assembly would require re-engineering the existing ASME Class 300 piping layout, modifying structural supports, re-running conduit/control wiring, and performing extensive safety re-certifications. The cost of engineering redesign and piping modification is estimated at and would result in unacceptable facility downtime of 4 to 6 months. KTM, Bettis, and Topworx are proprietary brands of Emerson. Emerson utilizes an exclusive territorial distribution model. Market research confirmed that Robert E. Mason & Associates, Inc. is the exclusive authorized factory representative and distributor for Emerson/KTM valves and actuation products for the Commonwealth of Virginia (where NASA LaRC is located). No other distributor is authorized by the manufacturer to quote or supply this equipment for delivery to Hampton, VA.
