Valves for Dryer 5

NASA Shared Services Center seeks replacement valves for Dryer 5, a critical compressor system component at NASA Langley Research Center, with proposals due July 6. This is a sole source procurement under FAR 12.102(a), with Robert E. Mason & Associates Inc. designated as the sole provider.

Place of performance is NASA Langley Research Center's Compressor Station in Hampton, Virginia. The procurement requires eight identical 3-inch rotary ball valves rated for 6500 psi at 500 degrees Fahrenheit, each paired with a 480V 3-phase electric actuator featuring 2-position functionality, fail-last-position operation, declutchable hand wheels, limit switch feedback, and torque detection. Valves must comply with ASME B16.34 standards and incorporate Single Piston Effect or Self-Relieving Seats for automatic cavity relief. Bi-directional sealing at 100 psi and uni-directional sealing at 6000 psi are required. The vendor must provide assembly and testing of actuator-to-valve packages, Material Test Reports, and other compliance documentation per NASA Langley LPR 1710.40.

Performance period is 20 weeks. The NAICS code is 332919, Other Metal Valve and Pipe Fitting Manufacturing, and the PSC code is 6695, Combination and Miscellaneous Instruments. The sole source justification rests on Robert E. Mason & Associates' role as the regional ValvTechnologies vendor supporting the Emerson product line at Langley, with system-design knowledge that alternative suppliers lack; competitive procurement would carry incompatibility and mission-downtime risks.

Interested organizations may submit written capabilities and qualifications by 7:00 a.m. Central Time on July 6 to Shanna L. Patterson, Procurement Specialist (Shanna.L.Patterson@nasa.gov). Submissions will be evaluated solely to determine whether competitive procurement should proceed instead. NASA FAR Supplement Clause 1852.215-84 regarding ombudsman protections applies.
