Among domestic valves, which positioner is used more, Wuzhong or Chuanyi?

Personally, I think Wuzhong's locator is the best. Of course, if you want to use it for a long time, it is better to import it. Azbil and koso (Japanese tooling) are cheaper, and fisher, Siemens and samson are even better than him. Generally, intelligent locators are above 10,000.
