METSO D201435L

Series:​ Neles Series 2000 / ND9000 family compatible
Function / Working Principle:​
Receives a 4–20 mA DC analog setpoint signal from DCS/PLC and compares it with the actual valve stem position feedback (via internal cam/lever). A digital PWM-controlled piezo or nozzle-flapper pilot stage modulates supply air to the actuator, driving the valve to the commanded position in closed-loop control. Supports auto-calibration and adaptive gain tuning.
