ROTORK- Linear travel positioner

Overview:

The ROTORK linear stroke positioner is a device used to control linear stroke valves (such as Angle seat valves, diaphragm control valves, etc.). It can precisely control the opening degree of the valve to meet the control requirements of different industrial processes.

Working principle:

The ROTORK linear stroke positioner usually adopts the feedback control principle. It receives control signals from the control system (such as 4-20mA current signals or digital signals) and compares them with the feedback signals of the actual position of the valve. By comparing the difference between the two, the positioner drives the motor or other actuator to act, adjusting the opening degree of the valve so that the actual position of the valve matches the position required by the control signal, thereby achieving precise position control.

Functional features:

High-precision positioning, multiple control modes, fault diagnosis and alarm, and rich communication interfaces
