Rotok Angle Travel Electric Actuator/Electric Device/Rotok Electric Actuator BRIA, BRIM Series Intelligent Rotok Electric Actuator is the world's top intelligent products. Advanced super-large-scale digital integrated chip, professional digital moment sensor and digital displacement sensor, all-Chinese menu operation and display, Mechatronics structure design, has created its perfect function, excellent performance, lightweight and beautiful, simple debugging and easy operation. It can be used in automatic control systems such as power station, petroleum, steel, chemical industry, oil pipeline, sewage treatment and so on. It can not only meet the requirements of frequent regulation control, but also meet the requirements of intermittent control. (Gate valves, globe valves, diaphragm valves, etc.)

BRIA and BRIM series multi-rotation intelligent electric actuators are driven by three-phase servo motors, which drive the hollow output shaft to rotate through worm gears and worm gears. In the reducer, there is a manual/automatic switching mechanism. When the switching handle is in the manual position, the operating handwheel drives the hollow output shaft to rotate through the clutch. When the motor operates the actuator, the manual/automatic switching mechanism falls back automatically. The clutch and worm gears mesh, and the hollow output shaft is driven by three-phase motor. At the same time, a force moment sensor is installed on the worm shaft of the motor drive, and the travel is transmitted to the position sensor through bevel gear meshing on the hollow output shaft.

The intelligent controller of multi-rotating intelligent Rotock electric actuator accepts standard analog current control signal or switch control signal. Compared with the position signal of valve position sensor, the output axis of the actuator is positioned relative to the input signal to complete positioning control, and can also be controlled according to interlocking. The two-wire control or event signal is located in the pre-set position of the control system. Unless the output shaft torque value of the actuator is greater than the rated torque value or the set torque value occurs during operation, the intelligent controller of the actuator will meet the requirements of the control system, generate correct instructions and trigger three-phase solid-state relay. The motor is connected with three-phase power supply to drive the normal operation of the actuator.

The multi-rotating intelligent Rotok electric actuator adopts non-intrusive design. The parameters and functions of the actuator can be modified or configured by the hand-held remote controller.
Standard code and name of this product: Q/ZTK 01-2009 Intelligent Electric Actuator
1. Main characteristics of intelligent Rotok electric actuator:
* Using large-scale digital integrated chip, it has powerful function and high precision.
* Mechatronics design, small size, light weight.
* Professional pressure sensors are used to measure the torque of the output shaft, which improves the accuracy of the torque measurement. The error rate is less than 5% and can be monitored and displayed dynamically.
Over-torque and blockage can alarm.
* The displacement sensor uses Hall sensor and digitally quantifies the pulse signal, so the basic error of the valve positioning accuracy is one-level accuracy.
* The function, parameter setting, debugging and on-site electric operation of the actuator are all set by hand-held infrared remote control without opening the lid.
* Full Chinese and character display, menu operation, intuitive and clear, easy to learn, understand and operate
