Valve Assembly

The Defense Logistics Agency Aviation is seeking to procure valve assemblies for F-16 aircraft under a limited source acquisition. The requirement consists of two distinct valve components: a normally open differential pressure regulator and solenoid-controlled shut-off valve (P/N 513000-2), and a solenoid shutoff valve (P/N 04-1001-25). This acquisition is being conducted under FAR 6.302 authority with only two qualified sources identified for solicitation. The Government will evaluate proposals based on price as a significant factor alongside past performance history. The solicitation (SPRTA1-26-R-0090) will be issued on January 22, 2026, with responses due by February 9, 2026, and award is anticipated within 90 days of notice issuance. Questions should be directed to buyer Micah Miller at micah.miller.5@us.af.mil, and all proposals received within 45 days of synopsis publication will be considered.

This procurement is not designated as a set-aside and will not utilize commercial item policies. The incumbent vendor is Essex Industries Inc., which previously supplied 14 units in January 2022 and 5 units in March 2023. The other identified qualified source is Transdigm Inc. The total requirement consists of 35 units, with the first valve assembly measuring 8.09" x 7.55" x 8.06" and weighing 1.5 lbs, while the solenoid valve measures 3.99" x 4.57" x 5.69" and weighs 1.2 lbs.
