Anyone know what this boiler part is?

Cos I think we need a new one. It’s leaking and is rusted inside. I’m just thinking it would help to be able to tell the plumber.

Honeywell 2 port motorised valve - hope that helps

I think there's someone on here called piglet John who's a plumber and really helpful but it won't let me tag him. Not much help. Sorry.

A zone valve it should have a cover on it and isn't looking too healthy!

Thanks, it’s got a cover but we took it off to see if there was an easy fix.

Thats really helpful.
