It was mainly junk, but there was a Honeywell two port valve in it, so I thought it would be interesting to take apart. The little correction I made in my schematic of a Type-S heating system was to take the pump/boiler switch feed directly to the live rail. If I'd left it as I originally drew it, then one valve actuating would have back-fed the other valves in the system and prevented them from turning off until everything else had turned off. Not a bad diverter valve. Rugged construction and quite easy to change the motor. If changing the switch take a photo of it first, and note that the motor has to be removed to remove one of the switch screws. Here's a link to the video I made about the three port Y-system valve. https://www.youtube.com/watch?v=lEOLyv5VcFM If you enjoy these videos you can help support the channel with a dollar for coffee, cookies and random gadgets for disassembly at:- http://www.bigclive.com/coffee.htm This also keeps the channel independent of YouTube's advertising algorithms allowing it to be a bit more dangerous and naughty.
