    Sunvic Zone valve replacement

    Sunvic Zone valve replacement 12th Mar 18 at 1:13 PM
    My heating is controlled by 2 Sunvic zone valves -1 for upstairs,1 for downstairs.Recently the 1 controlling the upstairs started not switching off. I removed the actuator head and sprayed it with WD40, whilst moving the gearing back and forth. I know that these valves are pretty useless and I guess that at some time I am going to have to replace it. There is no point replacing it with another Sunvic and I understand that the Danfoss actuator will swop with the same wiring. Can anyone recommend a Honeywell actuator head which will fit the existing base - if so, is the wiring the same?
