3 port on under floor yellow light blue valve

[southcoastboile]

I need to replace a 3 port on an underfloor circuit.

its blue and has a yellow light on top of the box.

does anyone know the make of valve and if I can replace with a standard 3 port?

thanks

Sounds like a blending actuator..... I would say no.

Okay thanks. Any ideas of the make? It's got a black bottom, blue top.

Sounds like one of the British Gas ones, which I think are re-badged Draytons. I seem to remember them having a yellow light but not 100% sure.

It's similar to that horstman one but not the same. I'm fairly sure it's just a 3port at her than a blending valve but not 100 percent and don't want the hassle of changing it and it not working I would rather do another job instead but I don't like letting customers down either
