DKZ-4200M electric actuator, thrust of 4000N, domestic series actuator.

　1、 Purpose:

The DKZ type linear 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 force and linear displacement.

DKZ 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.
