Product Details

ZKJ electric actuator, an execution unit in DDZ type electronic unit combined instrument, accepts signals from a regulating unit (or computer) and automatically controls the actuator to complete regulating tasks. It is widely applied to power stations chemical, petroleum, metallurgy, building materials,heat supply, water treatment and other industries.

ZKJ type electric actuator with various electric Manipulators can achieve undisturbed switching of"Manual-Automatic of the regulating system for remote manual operation on an object to be regulated in a timely manner.

All the actuator position transmitters produced by our company adopt the latest sensory packages be reference to the latest circuits of foreign companies, integrating power transformer, rectification, voltage stabilization, power amplification and constant current, the fabricated module (M) makes the reliability and stability of the actuator higher, so as to make the system more secure and reliable.

1.The product has reasonable structure, strict production technology and quality management, so that the high reliability of the actuator is ensured, with Mean Time Between Failure (MTBF) >25000 hours.2.The position transmitter switching circuit has high induced voltage resistance, and its performance exceeds similar products at home and abroad.

3.The travel control cams can be independently adjusted without interference, so that the adjustment is easy and convenient.

4.The AC single-phase motor is used in the high torque actuator to bring convenience to the use of the automatic control system.

5.The motor brake wheel made of special materials has the characteristics of reliable braking, long service life, and superior to similar products.
