Product features

Intelligent Proportional & Modulating Electric Valve Actuator

1.  1.3 inch OLED screen with high bright, energy saving and eco-friendly. Real time to Indicate valve opening position and external control command. Going into sleeping mode automatically after 5 minutes without operating.  The screen shows Valve opening position and external control command in sleeping Mode.

2.  Original valve adjustment complete by buttons - No need open Shell:

Step1: Adjust the valve in "anticlockwise full open position” by using the button to control valve and then Save;

Step2: Adjust the valve in "clockwise full close position” by using the button to control valve and then Save; 


3. With 16 digital High-performance CPU,12 digital high-precision AD conversion, built-in unique algorithm, Solved the problem of valve on/off inaccuracy caused by mechanical hysteresis. It is especially capable for 3-way valve adjustment.


 4. TFM200 total series and other DC24V series: built-in motor control module, motor frequency speed control can realize accurate positioning.


5.  Non contact positioning, control unit modularize design and potting processing, greatly improve product service life; Interface uses standard        connectors, convenient for installment, adjustment and replacement.

6.  Menu can report real time failure, including stuck or other reasons lead actuator fail to open/close valve integrally, and output failure warning signal.

7.   Menu can exchange control command.

8.  Menu can switch freely between remote control and local setting, and use button to Open/close valve manually.

9.  Menu can set valve close position deviation to on or off direction, greatly decrease the complex and inconvenience bring by “Normal On/Off mechanical positioning” to local valve adjustment.

10.  Menu can real-time adjust valve running speed of the actuator.

11.  Menu can restore factory default setting by pressing buttons.
