1.product introduction
YT-3400(YT-3450) Smart Valve Positioner accurately controls valve stroke, according to input signal of 4-20mA, which is being input from the controller. In addition, built-in micro-processing operator optimizes the positioner's performance and provides unique functions such as Auto calibration, PID control, Alarm, and Hart protocol.
