Abstract
Systems and method for shutting down a turbine, with the system including a housing defining first and second flowpaths therein, and an inlet coupled to the housing and fluidly coupled to a source of a fluid and to the first and second flowpaths. The system also includes a first outlet coupled to the housing and selectively coupled to the first and second flowpaths, and a second outlet coupled to the housing and selectively coupled to the first and second flowpaths. The system further includes first, second, and third control valves received in the housing and intersecting the first and second flowpaths. The first, second, and third control valves are each movable between a tripped position and an untripped position, such that if two out of three are in the tripped position, fluid is blocked from the first outlet and is directed to the second outlet.
