Dumpster-dive Honeywell 2-port valve teardown

I succumbed to temptation and dumpster dived a skip outside a neighbours house to see if there was anything technical in it. 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.
