2 Port 22mm Motorised Zone Valve Normally Closed 230v

Perfect, really easy to replace and great value

This unit is compatible with the original Honeywell power head for the V4073A valve and in some ways is built to a better standard, for example it has a proper plastic insulation tray under and around the electric circuit board instead of a piece of folded card. Operation is smooth and quiet.

These were easy-ish to install and seem to work fine. They're not Honeywell, but they seem to be totally compatible, with identical dimensions, wiring colours, etc.The only minor complaints are:- our Honeywell powerheads were mounted using T-10 screws, whereas these use normal cross-head screws. While that's nothing like a big issue, it does mean that when the valves are mounted in a hard-to-access location (as in our case), it's not always easy to tell what sort of screwdriver to use, as a lot is done by feel. So, if they need work doing in the future, there may be a bit of confusion when a T-10 doesn't work. Also, cross-head screws don't hold the screwdriver head in as firmly as Torx screws, which is a bit harder when working by feel.- the screw holding the cover on falls out when unscrewed fully. On the Honeywell powerheads, the screw is (deliberately) deformed so that it holds in the unit when it's unscrewed. Again, when you're working by feel, having the screw fall out is not ideal as it's pretty much impossible to put back in by feel. I ended up having to fit and unfit one of the powerheads three times because of this (so I could see it while I screwed the cover screw back in). (The screws connecting the powerhead to the valve itself ARE designed so those don't fall out, otherwise it would have been a nightmare).

Easy to fit onto the 3 way valve. Works OK. Good delivery

Excellent price, easy to fit, working with no problems

good quality product and fast delivery service

After fitting the valve, the heating still did not turn on. So the only part that would be faulty was the Nest Link. Google actually promised to pay for the engineer to come and do the test to prove, that the Nest Link is faulty. I got the engineer the same day, thank you very much, but he found out that the valve was faulty. That cost me £100 and new valve.Now I am out of pocket, at least the heating works.

Whilst it didn't solve my problem(think I need new valve as well) it was easy to fit and wire up and appears to work well. Next stage is work out how to change the valve without flooding the house🫣
