Flush valve for 50mm OD flush pipe?

[Mrflibble]

Does anyone know of a decent flush valve to fit the Ideal Standard SPACE cistern, that is better than the piece of carp fitted as OE please?

It has to fit onto the specific sized flush pipe which has an outside diameter of 50mm.

Many thanks.

Push button or cable push button type?

Siamp optima good valves, fluidmaster, Thomas Dudley, to name a few.

Cable/pneumatic push remote would mean I don’t have to worry about height.
I’ve looked at all of the usual types but they all seem to specify the cistern hole size but not the OD of the flush pipe...

What about this one? Macdee Pneumatic Dual Flush Valve - https://www.toolstation.com/macdee-pneumatic-dual-flush-valve/p86200

Looked promising but there’s a review that states 58mm outlet? And that it’s only suitable for close-coupled.

I think the fluidmaster pro550uk goes to 2”
