ROTORK- Angular travel positioner

Overview:

The ROTORK angular travel positioner is a device used to control angular travel valves (such as ball valves, butterfly 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 angular travel 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.
