Application
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 90 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 useof the ordinary quarter-turn electric actuator is avoided, which reduces thecost and improves the regulation precision.

Motor
According to the comparison result, the power is amplified to control whether the motor runs and the running direction.
Handwheel
Regardless of whether the remote control is disengaged or not, it can be safely switched to the manual state, and the local handwheel can be shaken.
Controller
In analog input mode, D-type controller (such as DFD-1002) can be connected to perform manual-automatic switching operation. Terminals 3-4 (ie SI) are input mode switching commands. When SI is disconnected, the analog input is accepted. Quantity input operation; when S1 is closed, it accepts manual switch quantity.
