Toilet fill valve - trying to identify part

[Jarvo273]

Hi

I have an old style toilet and the valve has failed but it's so old I can't find a replacement and don't know what to ask for.

Can any professional plumbers help me identify what I need to source?

Photos attached.

Thanks
Neil

Just replace the diaphragm rather than the whole thing! It will be MUCH cheaper & MUCH more environmentally friendly as the rubber of the diaphragm will be recyclable. #NoBrainer
