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

Used to repair Honeywell V4073A1039 3-port Mid-position valve (Y-plan). Warning: particular failed valve was over 25 years old (identifiable by not having a dimple on the top cover), it requires all four nuts to be removed to release the complete Motor head. This means a drain down or water bungs etc are needed to avoid water release. The later version with a dimple on the cover only needs two nuts to be undone to replace the Motor head and remains water-tight. This doubly makes the motor replacement the most cost effective and best course for repair. **Warning** Only competent persons should attempt this repair. Completely Power-off your heating system to isolate mains from the valve before opening valve cover (best remove fuse and safe-isolate). Remove two simple screws to release the failed motor which was clearly u/s as it turned by hand much easier than the new. Fitted the new motor and connected using Wago connectors - not the less positive wire-nuts supplied. Very pleased so far, as this high quality cost-effective repair option looks v.good so far. Valve control signals enabled the boiler to operate correctly so we have CH again.

Identical to the Honeywell, easy fix, £300 saved, highly recommended

Item is identical to the original other than pink not blue wires. Come with a single screw, crimp connectors and spade connectors. Slots into the fitting easily and secured with the single screw. Will see how long it lasts.

Worked ok

Very easy to fit works perfectly.Replacement motor on Sunvic 2 port valve

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).

value for money

Does not fit danfoss 2 port valves as supplied , i had to adjust it to make it fit.

Passt, erfüllt seinen Zweck und läuft immer noch.

Il motore funziona perfettamente, è praticamente uguale, c’è una piccola differenza di 1 mm sull’altezza dell’ ingranaggio, attenzione ho detto altezza non passo, quindi è praticamente uguale

Utilisé dans le cadre d'un remplacement de moteur de vanne 3 voies pour lequel Engie avait réalisé un devis de plus de 500€.Fonctionne bien mais a tendance a chauffer, pour ma part je lui ai "collé" un petit dissipateur thermique de processeur de pc afin qu'il chauffe un peu moins.Mis a part cela ça fonctionne, pour le prix et les économies réalisées, n'hésitez pas, j'en ai même pris un autre d'avance !A savoir : ce genre de moteur a une durée de vie limitée et finis toujours par lâcher (marche constante) au bout de deux ou 3 ans maxi. Donc en avoir d'avance est une bonne solution de dépannage.

Wenn die Heizung nicht mehr läuft, aber Warmwasser vorhanden ist, dann ist mit großer Sicherheit das 3 Wegeventil im Warmwasserboiler , bzw. der antreibende Stellmotor defekt. Das Ventil kpl. kostet ca. 180-350 Euro, der Ersatzmotor alleine 15- 20 Euro, Ausbau des Motors super einfach, viel Geld gespart!!!!O.a. Teil habe ich eingebaut (ca. 15 Minuten), super paßgenau und einwandfreie Funktion!Noch ein Tipp: bis der neue Motor da ist, den kleinen Stellhebel auf manuell (nach oben) schalten, dann werden beide Kreise (Warmwasser und Heizung zum Teil bedient) so kann man sich vorübergehend behelfen. Das ist aber keine Dauerlösung!!Habe mir bei dem Preis gleich noch einen Reservemotor hingelegt, (;-))
