An aircraft bleed system includes a low pressure supply port for delivering a first fluid at a first pressure. Also included is a high pressure supply port for delivering a second fluid at a second pressure, the second pressure greater than the first pressure. Further included is a feedback circuit in operable communication with the high pressure supply port for receiving the second fluid. The feedback circuit includes a first branch configured to route the second fluid to a high pressure control piston for manipulating the high pressure control piston between a high pressure closed position and a high pressure open position. The feedback circuit also includes a second branch configured to route the second fluid to a low pressure control piston moveably disposed within the high pressure control piston for manipulating the low pressure control piston between a low pressure closed position and a low pressure open position.
