Input Signal Conversion
Receive 4-20 mA analog current signals from the control system;
Convert it into a positioning action for the regulating valve to achieve precise control of the opening.
Intelligent diagnosis and communication (HART optional)
Support HART communication protocol for remote parameter setting, status monitoring, and fault diagnosis;
Can be integrated with DCS and AMS systems to achieve digital operation and maintenance.
High precision and responsiveness
Quickly respond to changes in control signals and maintain stable control;
Zero dead zone and low lag, suitable for closed-loop control scenarios with high requirements.
Equipped with LCD display (D)
It can directly display valve position, signal value, alarm information, etc., making it easy for on-site operation and maintenance personnel to view.
