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
Our company and tianjin university developed the electric actuator together, which fills the domestic gap. It was the fastest electric actuator in our country till now. The skj product series united with the butterfly valve form the electric valve with fast shutting off performance which is especially suitable for the work situation that needs urgently action. ¡¡¡¡the high speed series are widely used in the field of cement, the coal gas, agglutinates etc and was highly appraised by users.

SLM series is a new independent kind of multi-turn electric actuator. It applies to automatically control the gate valve, globe valve and so on which valve travel is beeline. It is widely used in such industries using pipeline as Petroleum, chemical industry, metallurgical industry, construction, municipal works, papermaking, fire power station and water power station etc. The basic model of series SLM products is outdoors model, with protection class IP65 ( if IP67 or IP68 is required, please put forward it). The design and the technical performances of SLM products accord with JB/T8528-1997 General terms of technical parameter of electric actuator for valve. Add electric controlling passive contacts, the capacitor for motor, the position feedback board, VOT , this improved the technical lever of the economic products , so that our customer can use products with excellent performance, fully function and reasonable price.
