Overview
DKZ linear turn is the earliest, only production electric actuators. It is the period of China's economic plan, the national jointly unified design products.
Our engineers earliest participated in this work,for DKJ, DKZ products to market have contributed,also for the professional development of enterprises laid a foundation.This product structure is simple, economical and practical advantages is the earliest use of state-owned large enterprises.
With the development of modern industrial computer management,Today, our DKJ, DKZ compared with the previous series,With 2 large substantial improvements ① produce directly affected by computer-controlled intelligent electronic type, outdoor type, flameproof and other improved products ② The circuit control section encapsulated in a small plastic box,Commonly known as modules, Forming a plug and play ease of maintenance,Adjusted higher accuracy and longer life.
Our products are the most standard installation dimensions, has played a role for many large enterprises renovation project.
DKJ,DKZ is the most simple structure product which our company produced,But escalating function,It has introduced new products. As long-term stability & outstanding supplier of DKJ,DKZ series products ,We follow the industrial changes,Provide long-term strength of protection for users continue to use the product and technical support.

Working principle
DKJ, DKZ series electric actuator is the terminal control device of industrial process measurement and control system,It is able to convert system control signals into angular displacement of the output shaft, linear displacement, to Control valves, etc.Closure elements 's position Or other adjustment mechanism,The controlled media work according to the system predetermined state.
Electric actuator according to control mode is divided by proportional type and integral type. Proportional type actuator is composed with electric servo amplifier and integral actuator, it could compare (closed loop control) system control signal and feedback signal of output shaft position,To change the stroke of the output shaft,to be Proportional relationship with output signal.Integral actuator is consisting of servo motor, reducer and position transmitter,it could work together with electric operater to achieve remote operation for valves and other Adjustment mechanism.
