Hi. I have a sealed heated water vessel with a Boss bzv222 motorised control (metal) which doesn't seem to be operating at all when the water heater is activated. No clicking, just nothing. Is this more likely a stuck valve, or could it be the control is just dead?
Hi. Pull the actuator off from the valve and check the spindle is free.
Hi I have Boss Therm BZV222. It states the actuator is BP2:DVA2/6. Your listing states Siemens DVA2/5 is compatible is this correct? Thanks Jim
Hi. As long as the white wire is not used, you can use the DVA2/5.
Hi my hot water system has a orkli 60520604 valve on it and when it calls for hot water the valve just keeps on clicking any help would be much appreciated.
Hi. It sounds like the gears have worn. Check this is not because the valve itself has seized before you change just the actuator.
Hello.My Siemens DVA2/5 intermittently clicks when HW switch is selected on my Honeywell ST9400C programmer. Also my Ariston Gas bolier keeps running so i have to manually shut it off.. Does it sound like I have a faulty Actuator ?
It does sound like it.
Would you have a replacement head for a Siemens Part ZA-V222C 2 port zone valve? Or would you have to replace the unit? Many thanks
I'm afraid not. A complete valve change will be needed.
I have a faulty Siemens BPZ CZV222 will this replace?
This is the replacement actuator for that valve.
Hi, will this actuator replace a head on a ZAV-222 (397749)??
Hi. I'm afraid not. A complete valve change is needed.

Hi, I have a faulty CVZ222 2 port valve. Will a CZV222 fit the same valve body? Thanks
Hi. Yes it will.
I have Orkil 60520604 head, this drives a round spindle with a slot in it, also has a normally open contact I have contacted other suppliers and they tell me that the part number ending 600 is a normally closed contact but you say it fits both, who is right? I need to order but unsure if this is the right replacement head. Please advise as nobody seems to have this replacement part. Thanks Richard.
Hi. This is the part you need, it will be a direct swap.
I have a Boss Therm / Siemens BZV 22 (plastic cover version) does the brass valve have the fixings as the newer Siemens metal cover and can I fit the metal covered actuator as a like for like replacement to the older plastic cover version.
No. You will need to change the complete valve.
Is this a suitable direct replacement for the Bosstherm BZV222?
Yes it is.
I need to replace an orkli 60520604 actuator, if possible. One of your answers for this above, is that it is a direct clip on replacement. That is great, however, are the wire colours the same, and if not, are they clearly explained in any instructions/wiring diagrams which come with the actuator? Many thanks
Yes, the wire colours are exactly the same.
I need to this replace the actuator on an Orkli 60520604 and one of your answers to questions says that this is suitable. Is it a direct clip-on fit with 5 wires which will fit on existing body without draining down? Thanks
Yes that's correct.
I need to replace two of these siemens CZV222 as the platic gears have broken. Have read that honeywell are superior actuator, can you tell me if there is a direct honeywell replacement actuator to this my installed siemens 2 port valve?
No, to fit another brand of actuator you will need to replace the whole valve.
Mine is a Orkli 60421600 on a 28mm valve. Would this be a straight swap? The white wire isn't being used. Are the wires and their colours standard so I could just copy the wiring? If this doesn't work then could I send the actuator back.
Yes, it will be suitable. The colours are the same. Please see for our returns policy.
