Valves for Dryer 5

This is a sole source procurement under FAR Part 12 for eight identical 3-inch, 6500psi, metal-seated rotary ball valves with Grayloc hub end connections, intended for replacement on Dryer #5 at the NASA Langley Research Center Compressor Station in Hampton, Virginia. The valves must be rated for 500 degrees Fahrenheit and handle air as the process media, featuring bi-directional sealing for 100psi reactivation and uni-directional sealing for 6000psi process air, along with single piston effect or self-releasing seats for cavity relief. Each valve must be paired with a 480V three-phase electric actuator offering two-position isolation, fail-last-position functionality, and a declutchable hand wheel for manual operation. The actuators require internal controller logic with limit switch feedback, torque detection to prevent overtravel, and no reliance on external PLCs. The contract requires full assembly and testing of each valve-actuator package as a unit, accompanied by compliance documentation per Langley LPR 1710.40 including Material Test Reports, and adherence to ASME B16.34 design and rating standards. Delivery is to be shipped to NASA Langley with an estimated lead time of 20 weeks, and performance is located at the specified site. The procurement is designated under NAICS code 332919 and issued by the NASA Shared Services Center through the National Aeronautics and Space Administration. The sole source determination is based on FAR 12.102(a), targeting Robert E. Mason & Associates, Inc., and the acquisition is non-competitive with no evaluation factors or weighted criteria. A pre-solicitation capability statement submission is required by July 6, 2026, at 7:00 a.m. Central Standard Time, emailed to Shanna Patterson, with oral submissions not permitted. The NASA FAR Supplement Ombudsman clause 1852.215-84 applies, and the contract type is combined, posted on July 1, 2026, under solicitation number 80NSSC26937183Q.
