Does anybody have an idea which if any actuators are a direct replacement compatible with this myson mpe322 3 port actuator ( also called act322 I bleieve)
Is there a sunvic actuator that fits or another .
Cheers
As far as I know the Potterton / Myson are the only heads compatible with that body. They are not the best and you can buy the complete valve and head for £36. I would change the whole valve and fit a Honeywell.
I did manage to fit a Danfoss actuator to one of these valves once - BUT it was a lot of work including the need to drill new mounting holes in the valve face plate - not something i would recommend
when getting a quote for a new head ask for the price of a complete valve/head assy as for some stupid reason they are often cheaper when bought as a complete head/valve - you can simply take the new valve off and just use the head on your existing valve body
Why do you want to have a different actuator? Why not simply buy another ACT322? I had to replace an ACT222 this week and my local Parts Centre had two in stock.
