Application
DKJ 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.
All the actuator position transmitters produced by our company adopt the latest sensory packages be reference to the latest circuits of foreign company.
