Product details
Product Introduction
Intelligent Valve Positioner YT-3The 400 series products are designed to control valve opening by receiving a 4-20mA current signal from a controller or control system
Set. Equipped with a built-in microprocessor, it can accurately control valve position and perform powerful functions such as automatic setting, PID control, and HART communication.
characteristic
Adopting a nozzle/baffle torque motor structure enhances the ability to resist dust, moisture, and oil stains.
●The product is equipped with a liquid crystal screen (LCD) on the outside, so the status of the locator can be directly confirmed on site.
●Through HART communication, various information about valves and positioners can be obtained.
●Valve position output module can be added to provide feedback on valve opening.
●Linear, fast opening, equal percentage and other flow characteristics can be set arbitrarily.
●The PID parameters can be easily adjusted through the buttons on the product, and 16 points can also be set to achieve special flow curves.
●Has excellent protection function (IP66).
