Bit of a long shot...don't suppose anybody has, or knows of any of these “old” Boss Therm (BZV22) 2 Port 22mm valves gathering dust by chance, trying to get hold of one seems a tall order ?
Needing to replace one for a relative as the plastic gearing has worn so it doesn't open completely, trigger the mircroswitch for the boiler and constantly “clicks” so was hoping for the easy option an just swap out the complete head unit without removing the valve.
The current Boss Therm BZV22 head is a different design so can't make use of the that, likewise for other mfr's.
Replacing with a complete new valve and motor doesn't look too easy a job as it's all quite tight with not much room but looks like that will have to be the way unless I can locate some old stock or a source for just the gear component if used on any other valves ?
Any help much appreciated, many thanks.
