sunvic sdm 1901 replacement

[rbrstr]

Can anyone please advise on a direct replacement. The actuator has failed and i would like to replace it leaving the brass 3 port valve in place, and avoid draining the system
there are plenty of sunvic actuators on ebay but i dont know if the mounts or wiring is compatible?

thank you

None of the Ebay actuators are suitable. They're for spring valves, yours is the hybrid momo. I don't deal with these, so not sure where you would source. No doubt someone on here will advise. A quick Google was no help.

If it were mine, I would bin the whole thing and go for a Honeywell 3 port mid-position valve. Not a difficult swap. Three reasons;

With hw and ch, pays to stay mainstream. Delays getting parts are never a good thing in winter.

Most plumbers understand more usual setups.

Sunvic stuff ain't quality.

Thanks for the response. Sunvic is garbage, 2009 I fitted that 3 port!
Honeywell it is then
