Obsolete 3 port valve ?

Malcolmkeith · 11 Sep 2013

The Honeywell 3 port valve on my heating system has part number 40003915-003. I can't find this listed anywhere so I assume it is obsolete. It was installed when I moved in 23 years ago so it's quite old now. It's now stuck with CH and HW both open.
Does anyone know if a direct replacement is available?
I'm guessing that it's not worth replacing the actuator on such an old valve even if one is available.

I don't think that is the model number more like serial number Honeywell valve model numbers tend to start with V40.
A common 3 port would be V4073A.

Thanks for the reply. It looks just like a V4073 so I took a chance and fitted one.seems to be working now..
