The DKJ-610M electric actuator has an output torque of 4000Nm and is a new type of modular actuator.

　1、 Purpose:

The DKJ type angular stroke electric actuator is the actuator unit in the DDZ type electric unit combination instrument. It receives signals from the regulating unit (or computer) and automatically operates the actuator to complete the regulating task. It is widely used in industries such as power plants, chemical, petroleum, metallurgy, building materials, heating, light engineering, water treatment, etc. It can output torque and 90 degree rotation angle.

DKJ type electric actuator, equipped with various electric operators, can complete the undisturbed switching of "manual ← → automatic" adjustment system, and timely remote manual operation of the regulated object.

The actuator position transmitters produced by our company all use the latest sensing components, referring to the latest circuits of foreign companies. They integrate power transformers, rectification, voltage regulation, power amplifiers, and constant current into one module (M) to improve the reliability and stability of the actuator, making the system safer and more reliable.
