Smart valve positioner, dust explosion-proof ExtD, angular stroke, double acting, failsafe, stainless steel corrosion-resistant
Installation of valve positioner
An essential principle of positioner installation is that the positioner, stem, and feedback rod should form a closed-loop negative feedback.
After the positioner is installed, the stem and feedback rod are not connected, and the feedback rod is rotated by hand. If the stem action direction is opposite to the feedback rod action direction, the closed-loop negative feedback is formed. The feedback rod and stem are fixed to ensure that the positioner works in the best linear segment. Locator installation is not correct, will also increase its linear deviation.
