Electric multi turn actuator

Product Details

Name: Multi turn electric actuator


GW series intelligent integrated electric actuator adopts advanced large-scale digital integrated chip, and has professional digital torque sensor and displacement sensor. The integrated structure design creates perfect function, excellent performance, exquisite appearance, simple debugging and convenient operation. The multi turn electric actuator uses a single-phase or three-phase motor to drive the worm gear and finally drive the valve stem nut. The movement of the valve stem nut causes the valve to open or close. It is widely used in power station, light industry, petroleum, metallurgy, chemical industry, oil pipeline, water treatment and other automation systems. This electric actuator has three control modes: continuous regulation, manual remote control and local manual operation, which can meet the requirements of frequent regulation control and intermittent control.



Simple mechanical drive, compact structure, non-invasive design, without opening the electrical box cover, you can set the stroke, torque and other parameters.

Mechanical torque protector, stable and reliable.

The protection grade reaches IP68, and the explosion-proof grade reaches Exd II CT4.

The torque measurement adopts electronic torque measurement mode, which has high accuracy, high reliability, strong adaptability, and can realize dynamic monitoring and display.

The application of super large scale integrated chips enables the actuator to have powerful functions.

Chinese and English menus are provided. The remote controller can be used for setting and debugging, and the operation is simple and convenient.

A variety of intelligent protection (power failure, motor overheating, etc.) and fault diagnosis functions.

Support bus (MODBUS, PROFIBUS, CANOPEN, etc.) communication function.



Gate valve, straight valve, regulating valve, knife gate valve, swing check valve, general valve, etc.
