What problems might exist with domestically produced intelligent valve positioners?
Thread Content
Hello everyone! What are people’s experiences with domestic smart valve positioners? Which one would be better?
Among the domestically produced smart positioners is Shenzhen Wanxun, which is a high-quality imitation of Siemens products and has also obtained relevant certifications. We haven’t used them, but we intend to try using a few in the future.
For domestic positioners, we have used products from Yueqing No. 9 Factory, and they seem to be fine; however, their adjustment accuracy is inferior to that of imported brands such as ABB and Siemens.
