Which valve brands are better, domestic or foreign?

Which valve brands are better, domestic or foreign? Used in the coal-to-methanol process. I want to set up an agency; could some seniors give me some advice? Thanks!
Newway in Suzhou is good at home. It’s hard to say about foreign brands; we use many brands, but in small quantities, and all of them work fine.
I only know that Newway and Su Valve in China are good, Zigong is also fine, as well as Global and Weilun
Abroad, we use Swagelok valves and they seem to work well; however, we only use small valves, 1/4 inch in size. Hehe, we’ve never used any large ones
There is basically no solution to this problem; there are many valves with different functions in the system, and without specific operating conditions, it’s inevitable that confusion arises. For example, both SWEAGLOG and MOGAS can be used in coal chemical industries, but they are not included in the same system or procurement package – how can they be compared?
