Generally it is set into the home position when it is manufactured. Wooden case

IT actuator is the part-turn electric actuator product, which can be used for controlling and regulating valves. The on-off product is appropriate for the application With 60 times of startup per hour, The regulated product is appropriate for the application With 1,200 times of startup per hour. Moreover, the control is more accurate and the positioning is more precise, due to increasing the intelligent control unit. The output range of the torque is 50 Nm (37 Ibf ft) - 2,000 Nm (1,476 lbf ft)

Summary DKJ quarter-turn electric actuator and DKZ linear-turn electric actuator are the earliest and the only products in our country. The products pool the wisdom of all the experts in our country during the planned economy time. Our engineers devoted themselves to this project in the early period, made great contributions to push the DKJ and DKZ series to the market and laid the foundation of enterprise's professional development. It is used in large-scale state-owned enterprise with simple-structure and economical and practical merits in the early period. With the development of modern industrialization and computer management, we make two outstanding improvements compared with the previous DKJ, DKZ series nowadays 1.We have already produced the electric intelligent type product, outdoor type, anti-explosion type and other improved products which are directly controlled by computer. 2.The steering circuit is fixed into a small plastic casing (generally called module), forming the PNP type that is easy to maintain. It functions as the higher regulating precision and longer using life. Our actuators have the most standard outlook size, which have played a key role in reconstructing projects of many large-scale enterprises. Principle of work The DKJ, DKZ series electric actuator are the terminal control device of industrial process survey and the control system, changing the system¡¯s control signal into angular displacement, linear displacement of output axle, the position of valve and other regulating units. The main purpose is to enable the controlled medium to work well under the regulated system conditions. The electric actuator is divided into the proportion type and integral type according to the controlling type. The proportion actuator is made up of electric servo amplifier and integral type actuator that can compare systematic control signal with the feedback signal (closed-loop control) of output axis so as to change the travel route and has proportion relations with the output axis signal. The integral actuator consists of servo motor, reducer and position transmitter. Coordinating with motor operator, it can control valve or other regulating units from long distant. wooden case
