Smart valve positioner, flameproof explosion-proof Exd, angular stroke, double acting, failsafe, split body anti-high temperature vibration
Torleo series intelligent valve positioner, a patented fast self-tuning algorithm, solves the problem of field application and commissioning of positioners and various valves. After the mechanical position of positioner and valve is installed in accordance with the agreed requirements (line travel, the included angle of feedback rod travel is required to reach 60 ° as far as possible, and the angular travel is 90 °), just press and hold the button shown in the left figure, release it after 3 seconds countdown, the positioner will start self-tuning, automatically judge the switching characteristics of the valve (air on or air off), and automatically calculate the up and down travel size and operation time of the valve Automatically judge the friction coefficient of the valve, automatically extract and calculate the characteristic parameters that meet the needs of high-precision control (0.1%-0.3%). The whole self-tuning process is completed within 3 minutes. All the self-tuning processes are dynamically displayed on the LCD screen, which truly realizes the visible fool operation.
