Abstract: An exemplary valve device for controlling flow of a turbomachine fluid includes a housing having a first inlet at a first elevation, a second inlet at a second elevation higher than the first elevation, and an outlet. A flow control member is within the housing. The flow control member in a positive g-force environment is biased toward a first position that permits flow through the first inlet to the outlet. The flow control member in a negative g-force environment is biased toward a second position that restricts flow through the first inlet to the outlet.
