Abstract
Quick disconnect devices for high pressure fluid transfer, and associated systems and methods are disclosed. A representative quick disconnect system includes a first connector and a second connector. The second connector can have an opening sized and shaped to receive a first end of the first connector. The second connector can include a poppet positioned to open the first connector when the first connector is connected to the second connector. The second connector can include an inner sleeve moveable between a first position wherein the poppet head forms a fluid-tight seal with the annular seat of the inner sleeve, and a second position wherein the second end portion is open to permit fluid flow through the end portion of the inner sleeve. In some embodiments, the inner sleeve is pressure balanced in every direction.
