DKJ electric actuator is an execution unit instrument in industrial process control system. It receives standard current signal, uses single-phase AC power as power, drives the motor, drives the output shaft to output angular displacement, and operates dampers, baffles and other adjustment mechanisms. It is widely used in process control systems in power, metallurgy, petroleum, chemical industry, light industry and textile industries. It has the characteristics of small size, light weight, full functions and easy use.
DKJ series electric actuator is an all-electronic new product by absorbing foreign advanced technology and applying new foreign technology and new devices, and it has modulating functions with integration of control circuit and the mechanism. It can directly accept DCS from a computer or 4-20mA or 1-5V from various regulating units,automatically control various dampers, valves, baffles and other regulating mechanisms without additional configuration of servo amplifier, and it can be widely applied to power stations, metallurgy, petroleum,chemical and other industries. It has the field manual function, so that the actuator can be adjusted in the field. If provided with DFD type electric manipulator, it can complete undisturbed switching of "Manual Automatic" of the remote regulating system and remote manual operation on an object to be regulated.

DKJ-B explosion proof type electric actuator is a DDZ type electronic instrument combination which accepts output signals from the regulating unit and automatically completes regulating tasks. The actuator is mainly applied to power stations, chemical, petroleum, metallurgy, mine and other explosion proof places. The explosion proof electric actuator is designed and manufactured in accordance with national standards GB3836. 1-83 and GB3836.2-83 for explosion proof electric equipment, and examined and approved by the national explosion proof identification authority.
DKJ-M electric actuator, an execution unit in DDZ type electronic unit combined instrument, accepts signals from a regulating unit (or computer) and automatically controls the actuator to complete regulating tasks. It is widely applied to power stations chemical, petroleum, metallurgy, building materials,heat supply, water treatment and other industries. DKJ type electric actuator with various electric Manipulators can achieve undisturbed switching of"Manual-Automatic of the regulating system for remote manual operation on an object to be regulated in a timely manner.
DKJ-Z electric actuator, an execution unit in DDZ type electronic unit combined instrument, accepts output signals from a regulating unit and automatically controls the actuator to complete regulating tasks. It is widely applied to power stations, chemical, petroleum, metallurgy, building materials,light industry and other industries. DKJ-Z electric actuator is directly connected with various butterfly valves, ball valves and other valves at the rotating angle of 9O for use. The direct mounted quarter-turn electric actuator is installed directly on the valve flange, so that the tedious work such as construction of a base configured linkage mechanism necessary for use of the ordinary quarter-turn electric actuator is avoided, which reduces the cost and improves the regulation precision
