A great replacement for broken valve actuators
A spot on like for like replacement. Turns out I didn’t need it as the problem was in the boiler itself, but it works perfectly.

Replaced the same type old one. Works as expected.

Good replacement part.
Good original quality, simple to replace (don't forget to isolate the boiler first though), and solved the heating coming on with the hot water. This same part was double the price from all my local wholesalers, and some of them had it on back order.

Don't forget to return the lever to auto after fitting.
Easy to fit and wire up. Don't forget to return the lever to it's auto position if you have been using it to give heat and hot water until fitting a new motorised valve.
