Butterfly Valve Project Photos.pdf

This document provides details for a federal construction contract opportunity to replace two 90-inch butterfly valves and control unit systems at the Cougar Powerhouse. The solicitation number for this project is W9127N21R0005 and is being issued by the Department of the Army Corps of Engineers Engineering District Portland. The butterfly valves being replaced are part of the main generating units at the Cougar Powerhouse and were originally installed in the early 1960s to shut off the penstock water supply to the turbines. Replacing the valves and associated control systems will improve reliability and safety as the current systems have become increasingly problematic to operate. The project scope involves construction services to perform the replacement work on the two butterfly valves.
