Analog signal drives the control valve to perform precise valve position positioning, displays the required opening and actual opening of the valve position in percentage, and feeds back the actual valve opening to the automatic control system with the same analog signal. It is an intelligent electric actuator that is increasingly widely used. It can be widely used in industrial process automation systems such as power generation, metallurgy, petroleum, chemical industry, urban water supply, smart buildings, and light industry.

Main features
' , Direct It accepts ~,~ or ~,~ analog signals from the automatic control and adjustment system. The built-in servo amplifier and manual automatic regulator do not need to be equipped with a separate servo amplifier.
' The upper and lower limits, stroke, zero position and full scale of the actuator can be set on the actuator operation panel.
' The CNC operation panel adopts a digit digital tube display with high definition. During operation, the input opening and actual valve position opening can be displayed at the same time, providing convenience for on-site monitoring.
', Control accuracy, dead zone is adjustable
', During the control process, it is equipped with interrupt signal self-locking and set value positioning functions.
'. It has fault self-diagnosis function. When a fault occurs, the operation panel can prompt the fault type.
' This machine has an automatic processing function for control input signal errors (including interruptions and disconnections). The user can pre-set the valve position opening and closing according to system needs.
' The servo motor is equipped with a variety of protection functions.
' The communication output port can adopt pulse width modulation, analog quantity, etc. Please specify the output method and protocol type when ordering.
