DKJ Quarter-turn electric actuator is an execution unit in DDZ type electronic unit combined instrument,accepts signals from 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-Automaticmatic"of the regulating system for remote manual operation on an object to be regulater in a timely manner.
All the actuator position transmitters produced by our company adopt the latest sensory packages reference to the latest circuits of foreign companies,integrating power transformer.rectification,voltage stabilization,power amplification and constant current,the fabricated module makes the reliablity and stability of the actuator higher,so as to make the system more secure and reliable.
