ABB V18345-1010521001

The ABB V18345-1010521001, or ABB TZIDC Electropneumatic valve posifier, is a smart device for precise control of valve opening. By receiving signals from the control system, it drives the pneumatic actuator to reach the set position of the valve, thus achieving precise control of the fluid flow, pressure or temperature.

Main function
Signal reception: Receive standard 4-20mA or digital signals from the control system.
Position feedback: Real-time monitoring of valve position by built-in feedback device or external feedback device.
Proportional integral differential (PID) control: PID control algorithm is used to achieve accurate control of valve position.
Fault diagnosis: Provides the self-diagnosis function to detect and display fault information.
Parameter setting: You can set parameters through software or buttons for easy configuration.
