About this file
This Statement of Work (SOW) details a procurement for two Steering Proportional Valves for the USCGC JAMES RANKIN (WLM-555), a US Coast Guard vessel. The urgent requirement stems from a recent dockside availability where a port z-drives hydraulic proportional valve failed, causing a major hydraulic fluid leak attributed to potential valve misalignment during system energizing. With the original equipment manufacturer (OEM) no longer in business and no replacement valves in stock, the vessel is unable to meet full operational commitments.
The SOW specifies that the replacement valves must be configured according to Controlled Enterprise Incorporated VS8640-VB131B specifications, compatible with the Z-Con/Tano steering system. The valves are to be shipped to the USCGC JAMES RANKIN in Baltimore, Maryland, with the vendor contact being MKCS BRIAN DALE. The procurement is urgent, with a request for shipping as soon as possible, and a required delivery date of 30 June 2025. The solicitation is issued by the Department of Homeland Security US Coast Guard, with the solicitation number 70Z08525Q0019390.
