On first impression these seem reasonable valves.
Contrary to other reviews both sealed okay for me at up to about 1.5-2bar of system pressure.
In terms of internal bore these valves are actually quite good.
The problem I found is trying to turn the screw to actually isolate with them!
You need to use a large screw driver and press hard to firstly overcome the resistance and secondly make sure the screw driver doesn't slip.
Use a 22mm gate valve instead.

I saw the other reviews on here but I've used these with no problems.
Maybe other people had a bad batch...

This is the worst ever isolating valve I've ever used. It will not seal properly.
Wish I'd read the previous review before I wasted my money.
Not fit for purpose!!!!!

does not do the job. Bought as a pair one would not turn off properly and continued to let water by. The other would not compress properly. Changed the olive changed the pipe put a wrap of tape on the third olive and it still leaked.
