Product Description

Samson 3725 Electric positioner valve positioner with HART communication


Product Introduction

The positioner ensures a predetermined assignment of the valve position (controlled variable x) to the input signal (set point w). It compares the input signal received from a control system to the travel or rotational angle of the control valve and issues a corresponding output signal pressure (output variable y).
