DKZ type linear 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,light industry, water treatment and other industries. DKZ type electric actuator with various electric Manipulators can achieve undisturbed switching of"Manual Auto" of the regulating system for remote manual operation on an object to be regulated in a timely manner. DKZ series electric actuator is divided into three types of products: electronically integral, ordinary, and explosion proof.
