Abstract: A bleed air selector valve allows selection and extraction of bleed air from a plurality of different engine bleed air ports to optimize engine efficiency and to maintain bleed requirements using a single line replaceable unit. The bleed air selector valve uses a relatively simple arrangement of poppets, check valves, and thermostatic compensation to augment high and low temperature to within acceptable limits. The bleed air selector valve significantly reduces weight, cost, envelope, and system complexity as compared to known two-port bleed systems with heat exchanger thermal compensation.
