Which manufacturers are used for actuator positioners of domestic control valves? Which domestic manufacturers produce good control valves?
For mechanical ones, Leyuan or Shangyi are good choices in my opinion; for intelligent ones, Yamata and Siemens are excellent options. What’s the name of that black-headed one with angular motion? I think it’s AEP
Isn’t Wuzhong good? Those who have used Baxter before have also used it for over a decade with no problems. It seems that most positioners are of foreign origin; even those made in China are imitations of foreign products. They have the appearance but not the quality – such fake foreign products are even worse than real ones.
It seems there are more from Siemens, and there are also quite a few mechanical SAMSON products
Wuzhong, Chuanyi – either one will do. Positioners from Yamada and Siemens!
There’s also Fisher, Samson
