This document is a Sole Source Justification (SSJ) for a Navy procurement of six A/C relief valves for Air Conditioning Plants aboard a naval vessel. The procurement is for a service order to open, inspect, and return six relief valves to their original condition, with specific technical requirements including 2.0 inch 150 pound IAW ASME B16 specifications, 150 PSIG maximum pressure inlet, and 75 PSIG minimum pressure relief. The valves are for a 250-ton Refrigeration Compressor system (Model #364-48921-000), and are proprietary to YORK INTERNATIONAL, now JOHNSON CONTROLS NAVY SYSTEMS LLC.

The required delivery date is 9/30/25, and the procurement is being conducted as a sole source acquisition due to the proprietary nature of the valves and specific technical requirements. The technical manual (S9514-EL-MMA-010) indicates these relief valves should never be tested or reset under normal circumstances and must be returned to the manufacturer for rework if opened. The valves are not commercial off-the-shelf items and must be manufactured or overhauled by the original manufacturer, which limits competitive bidding and justifies the sole source procurement approach.
