154 the design of valve 40 is considered compact and existing engine hardware does not require modification to accommodate an increased diameter 140 of valve 40 during assembly of valve 40 each hinge pin 92 is inserted through a respective sidewall recess opening 90 and through a respective control member 100 hinge pins 92 are then welded to securely couple each control member 100 within valve 40 in the exemplary embodiment hinge pins 92 may be removed to facilitate replacing control members 100 furthermore because valve 40 is fixedly coupled to duct 152 the orientation of valve 40 is maintained thus facilitating reducing valve petal flutter and failure and increasing a useful life of valve 40 during operation as fluid flows downstream through supply duct 152 and into valve 40 fluid pressure forces control members 100 to rotate from fully closed position 124 to open position 122 more specifically fluid pressure forces each members 100 to rotate until each respective member projection 119 contacts a respective flange stop 66 because each member portion 106 is curved and because each member is coupled to valve 40 within a respective sidewall recess 80 a valve effective area is facilitated to be increased furthermore the curved contour of each member 100 facilitates reducing fluid blockage through valve 40 as a result pressure drops across valve 40 are facilitated to be reduced and flow loss margins within valve 40 are facilitated to be maintained furthermore when fluid flow is reversed through a supply duct 152 or if a supply duct fails.
