Replacement Synchronous Motor for Motorised Valves ACL Honeywell Landis Gye Satchwell Sopec Tower Replacement Part 2-Port 3-Port Valve Failure

It fits perfectly the Head 4000 3916 - 001 of the Honeywell V4043H1056 (2-way zone valve). Price-wise, it is half the cost of the original one (I got it for £12, while the original is for £25). Replacing is straightforward (only one screw, and you don't even need to remove the head from the valve). The only downside is that it seems to be a bit more "rough" than the original motor (I suspect poor quality of the gear or the lubricant). I cannot assess durability since I just installed it (the original one failed after 4 years of operation, but based on the manufacturing date on the housing, it was already 9 year old).

So easy to fit, good quality and good price.

Last one lasted for 2 years but cheaper than the Honeywell ones.

Perfect

Bought one of these in 2022. It gave up the ghost last week so got another one. Dont know how long these are supposed to last but cheaper than buying a branded original and £12 for 2 years service is acceptable. If this one breaks in 2 years time I may look at a better version. Quick to fit and easy. Plumber would charge over £100 - that's a joke.

It fitted my Seimens valve OK.Thanks

Last one lasted me 4 1/2 years. Excellent value, easy to change, quick delivery, now have hot water again without an expensive engineer bill.

My Honeywell motorised valve developed an intermittent fault within a couple of months of being fitted. Testing showed that the motor was faulty, and this was an easy replacement.
