24v Zone Valve?

[Tipper]

My new control system for my UFH (Wavin/Hep2O) is all 24v output to the UFH loop valves.
I also have a radiator circuit for bathroom and cloakroom towel rails + one radiator in the utility room where the boiler is located.

It would seem sensible to use a spare UFH zone channel for this rad circuit. Therefore does anyone sell a 24v 22mm zone valve in the UK. I see on Google that they are available in the USA but don't want to get something that I can't get a spare part for in the UK

Any ideas?

Honeywell V4043 zone valve, get the 24 V ac motor, 40001011-002. A plumbers' merchant would order it.

Most commercial valves are 24 V ac, but stick with Honeywell for a domestic job.

Or go for abit of tuppaware and use a standard 240v valve, with a relay to operate it.

Thanks guys, that's what I was looking for. I'll go for the replacement Honeywell motor.

I thought I had the solution to my problem but no so re-opening this thread as I have now realised that the UFH control system is 24vDC and the synchron motor to replace that in the Honeywell valve is 24vAC. So that isn't going to work is it!

So back to the original question, who makes a 24v DC zone valve that is available in the UK?

Thanks in advance for your wealth of knowledge.

Sounds like you might be better off going with the suggestions above of using a relay to switch a standard 240V zone valve. And the advantage of sticking with easily available components


This one in a pattress box so is quite neat - operates on 24V DC and will switch 230V/8A.

Or something like this to mount on a DIN rail in an enclosure.

Are you using a spare zone on the manifold?
If so you will be able to get a 24v actuator from your local parts centre

These for example are 24v ac/dc

Yes, could run it off the manifold but then the rads would run at a significantly lower temp than they should, so not a good idea I feel.

Running at 240v would work and maybe what I have to do in the end. I just wanted to keep it simple and use available 24v circuit.
