The PT-2D-J single-phase regulating module is a new-generation single-phase integral regulating electric actuator special control module developed on the basis of the PT-2C-J module introduced by our company. It receives DC 4 ~ 20mA standard current signal from DCS or other systems or PLC controllers, and controls the electric actuator to complete the proportional adjustment of the valve opening degree. The product set, proportional adjustment, isolation amplification, valve position transmission, power drive and many other functions, with over-torque protection, electronic interlock protection, forbidden delay protection, loss of confidence protection, temperature protection and other perfect protection functions. . It can also be equipped with on-site button board to implement on-site operation and provide various alarm output; add valve position liquid crystal display to accurately display the valve position opening degree; add infrared remote control to achieve higher protection level on-site operation. The product has the advantages of strong anti-interference ability, reliable performance, shock resistance, moisture resistance, small size, simple wiring and convenient debugging. It has been widely used in DKJ, DKZ, DZW, LQA, QB, QT, SD, SM, SMC, SR, 2SA, 802, 903, 3410, 3610 and other products.

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
