Yes.
Are you sure it's 3/4" Looks like 1/2" to me, much more common in a house. The OD of the 1/2" BSP thread is 21.4 mm, 0.84".
Yes, the old valve has 3/4" fitting - bolt and nut through the water tank connecting to the Tee connector (3/4" in the centre). Not 22mm, not 15mm, not 1/2".
Search eBay for 3/4" ballvalve washers with no hole, and the price is between £6.50 - £10 each.

They look like for 1/2" valves which are more common. The one we have is definitely 3/4" valve.
What is the OD of the threaded part through the tank wall?
We decided to install the new PART2 valve when it arrives.
Will be taking out the old valve and just store it in the shed for repair through time.
What's the OD? That will settle whether it is 1/2" or 3/4".
They have both, same price.
It's 1/2 inch BSP...my fifty years tells me that. A 3/4 inch would have a bigger float.
Also , back in the day I would cut a washer down to fit what is needed here.
I just meant that it wouldn't fit solidly in the valve. There would be very slight movement up and down and, also, left to right. I'd expect the washer you've removed to have been jammed in, so the new would feel slightly "sloppy" in comparison.
If you put a half-inch washer in a three-quarter inch valve then I'd expect it to fall out, so that would be wrong.
I see what you mean. Yes, it would have been waste of time and effort.
I am waiting for the new 3/4" PART2 high pressure valve to arrive.
Or
I could fit 1/2" PART2 valve with a 90 degree reducer fitting as well. I already have a new 1/2 valve bought last time when the tank was over flowing, but didn't replace due to bending the old valve worked.
The only problem would be the tank hole too big for the 1/2 valve, which I might have to wrap around the valve fitting with loads of PTE tape. But not quite fancy doing it.
