Metso (Valmet) A413240 Overview

The Metso (now Valmet) A413240 is a positioner used to control the opening and position of industrial process valves. The positioner receives a signal from the control system and precisely adjusts the position of the valve actuator based on this signal, thereby controlling the flow rate of fluids.

Product Detailed Description

• Function:

• Receives control signals from the control system (typically 4-20 mA current signals or digital signals).

• Converts the control signal into an output signal (typically a pneumatic signal) required to drive the valve actuator.

• Precisely controls the opening of the valve to achieve the desired fluid flow rate.

• Provides a feedback signal of the valve position to the control system.

• May include diagnostic functions for monitoring the performance of the valve and actuator.

• Features:

• Robust and durable design suitable for various industrial environments.

• High accuracy and high reliability.

• Easy to install, commission, and maintain.

• Configurable control characteristics to suit different application requirements.

• May support multiple communication protocols (e.g., HART, FOUNDATION Fieldbus, PROFIBUS PA).
