Deskripsi
Intelligent Quarter-Turn Electric Actuator
Series : JD Series
Type : Intelligent Quarter-Turn
MFR : JINDA ACTUATOR
is the terminal control device for automatic control systems. It receives DC4-20mA analog signals or contact control signals from a DCS/PLC control system, regulator, or computer, and outputs torque to complete automatic control tasks. It features fast signal transmission, convenient centralized control, sensitive operation, high adjustment accuracy, simple installation, and easy maintenance. It is suitable as an actuator unit for controlling or regulating various butterfly valves, ball valves, dampers, and regulating valves in open-loop or closed-loop control systems.
