The valve leaked, the motor got wet, now it's dead. It looks exactly like the 'Drayton' one that SFD and everyone else sell as a "replacement for most common motorised valves" - same mounting points, same shape, same power, same colour wires When I came to replace it though I discovered that the driving cog is the same size with the same number of teeth but the shaft is 3/4" long on the original and 1/4" on the replacement. Also, tragically, the cog rotates anti-clockwise viewed from the cog side on the replacement but it needs to rotate clockwise. The other difference is that the original motor is 6.7 rpm and the new one is 5 rpm, but I can probably live with that. Does anyone know if any other commonly available boiler uses a motor like this? I can't believe they had a motor specially made for this one application. Before you tell me to just replace the whole actuator, ECO HT want £100 for it. There must be a cheaper option that that! Funnily enough, the SFD motor is packaged as Drayton but is actually made by Synchron in the USA and the burned out motor is made by Cramer, also in the USA. And there I was thinking everything was made in China these days.
