3720 Part-turn Electric Actuator For Ventilation Valves

3720 Quarter-turn Electric Actuator

Functions and features of 3720 series intelligent electric actuator:

Control module adopts advanced hybrid integrated circuit, with powerful functions.
Non-intrusive remote control operation function: parameter adjustment and setting without opening the cover, on-site manual operation, output contact feedback and display of manual/automatic working status.
The control module adopts menu setting, simple and convenient parameter setting and function adjustment.
Input signal setting function: choose analog control (DC4~20mA) or switching control (AC220V) according to the working condition, wiring is independent and does not interfere with each other, both can output DC4~20mA feedback signal.
Valve position display and fault alarm function with input signal and valve position display function, and signal, manual/automatic, positive/reverse action, limit and fault indicator.
Action time, action number memory function.
Calibration function of input signal and feedback signal to improve control accuracy.
Anti-interference function: set reverse action delay time to avoid reverse shock.
Zero point and stroke calibration, convenient and accurate, can be set at any position.
Four state settings for SMS: fully closed, fully open, self-setting (full stroke), and keep in place.
Electronic limit function: with in-place contact feedback
Fault self-diagnosis function: can self-diagnose the fault phenomenon to protect the actuator.
Overload protection function: overload protection time can be set according to the need.
Temperature protection function: temperature protection switch is installed inside the motor to protect the motor from being burned.
Embedded click structure, reasonable overall design, compact mechanism, small size, pro-weight and good heat dissipation.
The actuator is self-locking after power failure.
