The plug has residual pressure trapped behind the primary
valve, while the coupler has no trapped pressure.
Stage 2: Plug Chamber E
vacuated
The plug valve is opened, then the socket valve opens,
evacuating the plug chamber to the unpressurized socket.
Stage 3: Release Pressure
The connection continues, with the Equalizer valve being
activated, releasing the trapped pressure into the plug
chamber, then to the unpressurized socket.

The primary valve can now open easily, since there is no
longer any pressure trapped behind it, allowing the socket to
fully engage the plug.
