How to check a 2 port zone (Honeywell type) valve is working

Hello. Many thanks for this video. my Honeywell valve seems to be making a metallic clicking sound whenever switched on? Do you think replacing it would solve the issue?

And what would be reason, when valve is energised I cannot move the valve freely and neither open it manually. But when de-energised I can manually open it.

I have one of these connected to a tank in cupboard, how hot can this unit get?? Ours is super warm to touch

Hi I have this one and rads get warm when water is heating up in tank …. And everytime I put that switch to auto it springs back like in video if I change the motor will this solve the rad issue thank you

How did you wire it to test whether it energises. There are 5 wires. Blue and yellow seem logical but orange, grey and brown. Do you just wire to a plug, which is live??

Thank you for making this video! My sliding mechanism will never move to the "manual open" side and I suspect that this valve is stuck closed (part of radiant heating system - pipe below valve is cold). Other zones work fine and are hot. Do you know if there are serviceable parts within the valve or anyway to open manually? Thanks!

Hello, my new motor valve opens manually before connecting to the wires but once connected it wont open manually not auto. I thought the old motor valve was the culprit but with new motor valve it does the same thing. local plumbers cant figure out what the issue it. What could be the issue here? Another motor valve opens ok manually but not opening on auto. Could this be the wire/electric cord issues?

Helpful. Thanks.

Perfect. Thanks so much for this.

This is a good to know test and you demonstrated it very clearly. Well done and thanks.

I have the same zone valve, mines moves across manually to open freely ( energised ) & closes itself, however doesn’t go into the open position automatically. What could be causing this?

Thanks

Great - I have had problems with a number of zone valves where the tap itself has got a bit stiff and this has caused the place where the zone valve keys into it (invariably made of plastic) to 'round out' and not be a tight fit - then you get all sorts of intermittent problems. Probably down to hard water jamming up the actual tap valve. One to look out for!

Hi, if there is a constant clicking noise when the themostat is triggered on, what does this mean. It goes off when not on but has been clicking ever since yesterday for the upstairs heating.

Hi why is it when I leave mine on automatic then only downstairs radiator comes in but when I put it on manual both upstairs and downstairs radiator comes in perfect

Excellent mate, saved me a small fortune!

How can you tell if the valve is open or closed?

there's is a 3 port valve. if I put it back on manual can I leave it there

Guys I have old school back boiler and tank in airing cupboard. got hot water and one radiator small room getting mild hot others not in house. however all piped near tank hot any ideas?

Thanks for the video , I tell you my problem .... I have a horstmann 2 way valve and have 3 heating selections , upstairs, downstairs and hot water .. If I select hot water the downstairs rads heat up also , downstairs is working when selected also however upstairs heating has stopped working unless I override it with the Lever .

Thank you very much for your video. And what should K do when it’s make a lot of noise? When K try to switch on the heating, it doesn’t work and I here “tac” “tac” “tac”

How do u get 18000 views I work with this kind of actuators myself n did not know that many people were interested in a Honeywell Valve Actuators 😏

And if the slider is loose when deenergized?
