A valve device includes male and female housings having, respectively, exterior and interior annular channels. The male housing is receivable into the female housing such that the exterior and interior annular channels together define a toroidal tube. The male and female housings together define a fluid through-passage. There are first and second valve elements disposed, respectively, in the male and female housings. Ball locks are receivable into the toroidal tube. The ball locks axially lock the male and female housings together but permit rotation between the male and female housings. A lock includes first and second pin holes in, respectively, the male and female housings. The lock is engageable to rotationally lock the male and female housings when the first and second pin holes are in alignment.

A valve device () includes male and female housings () that together define a fluid through-passage (). The male and female housings have, respectively, exterior and interior annular channels (). The male housing is receivable into the female housing such that the exterior and interior annular channels together define a toroidal tube. First and second valve elements () are disposed, respectively, in the male and female housings. Ball locks () are receivable into the toroidal tube and axially lock the male and female housings together. A lock () engageable when the first and second valve elements are in functional alignment and which when engaged rotationally locks the male and female housings.

A flow control system () includes a fuel passage network () that has first () and second () network portions that are in a parallel flow arrangement with each other. A fueldraulic device () is located in the first network portion. Operation of the fueldraulic device varies flow through the first network portion. A flow restriction orifice () is located in the fuel passage network and is arranged in series with, and upstream of, the fueldraulic device. The flow restriction orifice is operable to generate a pressure differential that varies responsive to the flow through the first network portion. A flow control valve () is located in the second network portion. The flow control valve is operable responsive to the pressure differential across the flow restriction orifice to control flow through the second network portion.

A valve assembly includes a valve body, a first spring seat disposed within the valve body, a preload spring disposed within the valve body and mated with the first spring seat, and a second spring seat disposed within the valve body and mated with the preload spring. The second spring seat is adjustably mated to the valve body.
