380VAC Part-Turn Electric Actuators Control Valve/Valve Actuator/Industrial Actuator/Bernard Actuator/Rotary Actuator

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 DKJ Part-turn and Linear-turn products has 30 years produce history, they have the advantage of simple structure, practical and economical use. Utilized by many large state-owned enterprises 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
