Hi
I have found out that my 3 port mid position valve is nt working and have to buy a new one. It is a Landis and Gry MAV 322 I think it has 22mm connections on it.
It seems you can no longer get these but may be able to get a similar one from siemens. But these do not have the removalbe box on top so if it goes again i will have to replace the whole thing again. (Drain the system and everything...FUN!!)
Does any one have a good suggestion for a replacement for this
Thanks
Cooper
