TZED120 series wide door positioner is a high-precision, multi-functional industrial control device. By receiving the pneumatic or electrical signal from the control device, it accurately adjusts the supply pressure of the control actuator, thereby providing the adjustment rod position proportional to the input signal, ensuring accurate positioning and control of the wide door. With high precision, large stroke range, low air consumption and simple debugging process, the efficiency and quality of industrial production are significantly improved.
