Described are two parts of a disconnect for a hose carry poppet valves that open when the coupling is made and close when the coupling is released. One of the two parts of the coupling has external threads and the other part carries an internally threaded collar, and the two parts are threaded together like a garden hose. The two poppet valves press against each other and as the threaded collar is turned the two valves are gradually opened. These components are conventional. The two valves can be opened only partially for a throttling effect which is useful in balancing parallel chilled paths for cooling a data processor. A valve position scale is marked on the threaded part to show the number of turns that have been made. The scale is read at the edge of the threaded collar.
