Hot water mixing valve

[Chalked]

Doing some alterations t a house with a wood chip boiler that feeds a large buffer tank, this has a coil for hot water that is then circulated round the property.
the hot water is very hot (70*c)
can I fit a mixing valve at the cylinder between the cold supply and hot take off .
if so can anyone recommend a decent one.

thanks

If you want to go motorised, look at an Esbe CRA controller with a VRG valve on the back of it.
If you want to go with a manual one something like an Esbe VTA 313 should see you right.
