A valve flange joint includes a valve flange (14) and first and second duct flanges (16a, 16b). The first and second duct flanges (16a, 16b) include respective first and second mating portions (17a, 17b). The first mating portion (17a) includes a first duct rim (20a), a first duct face (34a) in contact with a first face (30a) of the valve flange (14), and a first slot (22). The second mating portion (17b) includes a second duct face (34b) in contact with a second face (30b) of the valve flange (14), and a second rim (20b). In an embodiment, the valve flange (14) includes a tab (18) that extends in an axial direction through the first slot (22) and includes an inner surface radially inward of an outermost portion (46b) of the second mating portion (17b). In another embodiment, a first thickness (T 1 ) is defined between the first flange face (30a) and the second flange face (30b). Second and third thicknesses (T 2 , T 3 ) are also defined for the first and second mating portions (17a, 17b). The three thicknesses (T 3 ) are substantially similar. |
