IMI Critical
March 16, 2023
The Challenge
The South American combined cycle plant was facing problems with two of its competitor installed 1-1/2” ANSI 600 class feedwater valves in an intermediate pressure (IP) application. The valves did not perform well in start-up conditions and the valve trim was being adversely affected by cavitation. Multiple upgrade solutions from the incumbent supplier continued to fail.
