Working principle of valve positioners
Thread Content
There are many brands of smart locators available these days, and I would like to know the principles behind these smart locators as well as the methods for calibrating them.
It’s over 50,000 pigs – you couldn’t catch them all even in three days! There are so many brands and so many models – it would take three days just to list them all. At least give me some model names; otherwise how can I help you?
There are too many brand models; there’s nothing at all 😭
The principle of positioners is basically the same everywhere; it can be found by searching online. Is it still necessary to explain this? I don’t understand what you mean by the verification method? Tune? Different brands have different methods; they’re all unique
