Stable performance Favorable price Great sales volumes Several protection function Intelligent and multiple accuracy control

 Summary

The electric actuators we manufactured are the products by using the introduced advanced technology from Europe advanced technology.

It has various kinds of protection function and control mode. It can be divided into the part-turn series, linear-turn series and multi- turn series. There are more than hundred kinds of specifications. Its control main board is continuously upgrading and updating and the new products appear rapidly in order to satisfy the needs of modern industrialization.

The electric actuator has already widely applied in the large and medium-sized project which is the newly built and was highly appraised by users.

At the same time, we also accumulate rich technology and scene experiences in the process of updating and upgrading DKJ or other actuators to the introduced series.

 

Features of the introduced series

Cut-off signal protection

The actuator stop at the original, all-on or all-off position which is instructed by users as the signal is interrupted by accident or the input signal is less than 3mA (called the cut-off signal) in order to guarantee the whole system’s safe and stable. It also possesses the output connection point for alarm.

Over-torque of two- way protecting function

The actuator has an over-torque surveying device that can accurately survey the torque of the valve. When the torque exceeds the setting scope, the torque switches inside the actuator and outputs a signal to the controlling circuit for stopping the motor to protect the valve, the driving parts and the motor. After the mechanical over-torque fault is relieved, shutting down the power supply or input an instantaneously reversed signal, the actuator will come back to turn normally.

 Auto switch function

The actuator can implement three kinds of switch function – “Distant- automatic / distant -manual /local”. It can also operate electrically and manually on the spot.

The pros and cons of switch function

The control panel program has the pros and cons of switch function that satisfied different situations on-the-spot.

 Dynamic braking

The control panel program of modulating model electric actuator has the dynamic braking function that can prevent motor’s inertia movement and ensure the stability and reliability of the controlling system. 

Servo-motor with double protection and high-efficiency 

All the motor has the thermal and open-phase protecting function. When there is an unexpected failure, it will shut off the power supply effectively so as to protect the motor. It serves as a good servo characteristic and it will not overheat after frequent movements.

Stronger anti-interference function

With the imported main chip of control panel and stable performance, the actuator has the stronger anti-interference capability. The input and output signal adopt the shielded wire.

It has PROFIBUS-DP universal bus interface,two way digital communication function

The operator can realize the field control, remote programming, function combination, on-line   monitoring, fault analysis,operation maintenance in the control room.

It is more advanced, convenience, and reliable
