Key features and functions: It receives 4–20 mA current control signals to precisely control the valve; it features an electric conversion mechanism with shock resistance; its modular internal structure reduces the likelihood of failures and facilitates maintenance; it provides valve position feedback for monitoring the valve’s opening degree within the control system; it has 4 buttons that allow for automatic setting, and the status of the positioner can be checked directly on-site; it comes equipped with a high-backlight LCD screen that supports Chinese display, consumes little air, and is cost-effective; it has a protection rating of IP66
If it were me, I would prefer to use domestic intelligent valve positioners. Because it has the following main features and functions: it receives a 4–20mA current control signal to precisely control the valve ； Electrical conversion mechanism with seismic resistance ； The internal structure is modular, which reduces the likelihood of failures and simplifies maintenance ； Supports valve position feedback output for the control system to monitor the valve opening degree ； It has 4 buttons that allow for direct verification of the locator’s status on-site ； Features a high-backlight LCD screen that supports Chinese display ； Low gas consumption and good cost efficiency ； The protection rating is IP66. These features endow domestic intelligent valve positioners with significant advantages in terms of performance and practicality. .
From the perspective of product quality, imported brand positioners have good quality and a low failure rate. If working on a project, the price of imported brand locators isn’t exorbitantly high either.
We have used many products from the Wanxun and Rotok brands in the past, and they were fine.
It’s already the year 3202 – there’s no need to be overly obsessed with imported brands. In my opinion, for routine maintenance, the spare parts for imported brands are too expensive, making repairs uneconomical; domestic alternatives should be considered instead.
Another reason besides the low price: lol:lol
I’ve used Chuanyi products; they’re okay in normal use. It won’t work when it’s very cold; it’s probably a problem with the sealing gasket.
