Danfoss Randall HS3 22mm Motorised Three Port Mid-Position Valve

[Buck Taylor]

recurring Issue, any help would be greatly appreciated.

I have changed this valve twice in the last 3 years........ is this normal or would i expect to get longer use out of this valve?

I would get rid and fit a Honeywell or a Drayton valve. I would have expected them to have lasted longer, did you change the whole valve or just the head?

Thanks. 1st time I changed both head and valve 2nd time just the actuator. Are both the Honeywell and Drayton compatible and like for like (4 wires and dimensions)?
Thanks
