Replacement Synchronous Motor for motorised valves ACL Honeywell Landis Gye Satchwell Sopec Tower DIY Replacement 2-Port 3-Port Valve Failure

Product Information

Travis Perkins were selling BOSS brand genuine SYNCHRON motors in the past but their web page photo now shows what looks to me like a cloned motor. There is always an open pathway from port AB to port A or from port AB to port B or from port AB to both ports A and B at the same time. In larger properties, 28mm valves may be used (the 5-wire 3-port V4073A1088 and the 6-wire 2-port V4043H1106).

The spindle in Drayton 2-port valve bodies only turns through about 30º (this angle is about 5 minutes on a clock face).

Occasionally we come across a Honeywell motorised valve where the powerhead jams but the spindle (actuator shaft) is still free. On earlier motorised valves, these were both joined to other wires using metal crimps encased in plastic. The small gear wheel on the Synchron motor fits into the round hole which has black grease round it in this picture.

When Heating and Hot Water are both selected, the valve drives open to the mid-position and stays there.the honeywell motorised valve (model no: V4043H1056) is only working in manual mode so i figure the motor needs replacing. Anyone who has been in this game long enough will know that the honeywell motorised valves are by far the most reliable, which is helped by their rubber ball technology as opposed to 'rotating shoe' type water sections.

Motorised valves are often fitted in tight spaces with limited visibility so note the orientation of the powerhead.

These danfoss motors are not replaceable and the whole actuator head has to be replaced when faulty - truth is on these valves, you need to replace the water section as well - with the honeywell you don't. no chance taking the motor back (i had to take off the clips at the end of the leads and join wire to wire with those plastic cover things that are included). It doesn’t matter which of the two motor wires is connected to which of the two free powerhead wires as they are polarity free.The orange valve wire may have a potential of 230V but this is coming from the cylinder stat (to which the orange wire is also connected) and not from the circuitry of the valve.
