"4 for reliability only because just installed. Read many of the other reviews so felt quite confident I knew what was wrong without even testing, but did and found the wire to the motor was live when thermostat was up and not when down. Yes I might have saved a £ or so going elsewhere, but ordered and collected (even with cycling to Screwfix) in 30 mins. Then about 10 mins to fit and with the little caps included, didn't even need soldering. Time will tell how long it lasts (Interestingly I have 3 two way valves, one each on two HW tanks and on for the CH. the two that are 10 yrs old are going fine, it was the one added 5 years ago that went)"
"I found these genuine Syncron motors here a year or so ago after using Chinese copy versions from a nation wide plumbers merchant. The copy versions only seemed to last a few months, one failed after 5 weeks, not very good for your reputation!! I have not had a call back since I have been using these and would recommend them to anyone. They will fit just about every make of motorised valve."
"Decided to take a gamble and replace my Honeywell motor after reading customer review, it was very easy to fit, fitted perfectly and is working well, saved replacing the valve and was half the price of Honeywell Motor replacement."
"Have successfully used this motor for several different makes of motorised valve, both 2-port and 3-port. Although specified as Drayton, most recently fitted one to a Horstmann Z322. As the valve still functioned manually. I intended to change the detachable head, but a change in design meant this was not possible, so changing the motor was an alternative solution. Indeed, it was probably quicker than changing the head as I only had to reconnect the two wires to the motor rather than rewire a new head into the control centre. Does involve soldering in the Horstmann, though."
"I used this to replace a worn out actuator on a Salus MV222 motorised Valve, If fits perfectly, I used the 2 bullet connectors to connect the 2 red wires to the small PCB on the valve. Many thanks Screwfix, you saved me from replacing the whole valve which is no longer available !! Only just installed (took about 15mins) so cannot give 5 stars for reliability as yet !"
"After fault finding to the valve, was advised to swap out the entire head unit - this was a better and far cheaper option. Bite the bullet, it took me less than 10 minutes after isolating the circuit to have it back working."
"I had a Honeywell valve that had failed and had intended to replace the whole item until I saw the price. Realising it was possible to replace only the motor, I confirmed that it was indeed the motor that had failed and ordered the replacement unit. It was an easy and perfect fit. I'm really pleased with the result and have saved a considerable sum of money. As it has only been fitted for 3 days I have been a little cautious with the my rating for Reliability but have no reason to suspect it will be less than 5 stars in the fullness of time. Highly recommended for a replacement in the Honeywell valve."
"After a lot of searching established that the likely reason, the boiler was only firing up and giving me hot water when the central heating was on, was a faulty motorized valve. Comparing the price and effort of replacing the entire unit (a Honeywell V4043) or just the synchro motor for £13 it seemed worth hoping that it was just the motor. The motor is held in by one screw and the gear mechanism, straightforward to replace with the new one. The replacement comes with spade clips attached to the wires but it also has two bullet terminals in the pack which I needed to connect to the Honeywell, Also the Honeywell says it is 6.5W whereas the Drayton is 4.5W but it seems to be working happily, boiler now firing up for hot water."
"When I worked out that it was the motor on the motorized valve that was faulty. I googled to find that it kept saying replaceable motor but could not find one for the actual valve maker.. So I just looked for motorized motor for Valve and came up with this. Was also very pleased to see it came with connectors which had got me concerned, as Screwfix only sold in bulk. Less than thirty mins of work sorted out the problem. Very satisfied"
"My radiators kept getting hot when only the hot water was selected. Via internet blogs found this little motor readily available and easy to replace and likely cause. Making sure I isolated the boiler system electrics, I followed guidance on pack and You Tube. This little motor suits many valves including mine, a Siemens DVA3. Problem solved for me any way."
"I had feared that a Siemens valve failure would need me to replace the whole body. Pleased to see that the actuator is readily available, that was all that was needed and it fitted straight in and worked. Amazing to see a device not made in China (It is USA)."
"I recently had a Synchronous Motor failure which stopped several radiators working. After several tests of the system I discovered that it was the motor and is definitely needed replacing.
My first port of call was the Screw Fix website. It offered the correct information needed and a great discounted price.
The Drayton Synchronous Motor was extremely easy to fit, The Lugs on this replacement motor aligned and matched the Honeywell Synchronous Motor threaded holes and the unit took approximately 5 minutes to fit.
I cut the the cable ends and used the supplied wire protective caps to join up to the existing wiring, I switched it on and it worked first time.
"This motor was a direct replacement for the one in my Danfoss HP22 two way valve. As some other reviewers have said the usual problem is not failure of the motor itself but the small drive gear which over time is prone to high wear that can ultimately result in the valve 'hanging up' and therefore not operating the micro-switch that shuts the boiler down.
The kit from Screwfix also included two new crimp connections and new securing screws. In addition, the replacement is made in USA as per the original item. Obviously its too early to comment on reliability but I would highly recommend it."
"Don't know what other people's valves are like,mines is a danfoss. Reading other reviews and being an engineer I thought this would be an easy 5 min job as said by some but it definetly wasn't.
Product is a direct replacement for the motor already in my danfoss valve and is very simple, yet a little fiddly, to replace. Comes with crimp connectors supplied. For the cheapness of the item compared to a new valve I give it 5 stars.
Should maybe be added to description that soldering may be required. Lucky I had a soldering iron!"
