Working principle
Signal input: The control system sends a 4-20mA signal to the locator.
Position comparison: The locator receives feedback signals and calculates deviations by comparing them with the set values.
Pneumatic output: The locator adjusts the output air pressure to drive the thin film actuator.
Valve position adjustment: The valve stem moves to the target position, and the feedback signal is updated in real-time to form a closed-loop control.
Core advantages
High precision: Positioner+feedback can achieve a repeatability accuracy of ± 0.5%.
Stability: Eliminate the influence of friction and pressure fluctuations on valve position.
Remote monitoring: The intelligent locator supports parameter configuration, diagnosis, and fault alarm.
Safety redundancy: When there is a gas/power outage, a fault safety position can be pre-set.
