The handler for the ghost of a valve (objects 68 to 6B). It hovers over the socket which comes before it in the table of objects, and is created by HandleSocket. It retires itself if there are special objects in the room. It stays for a couple of frames in IX+10, then changes into its sparkle form (see HandleValveGhostSparkle).
