Product Name : CTF001 4-20mA



1. Simple design, compact size, 4-20mA adjustment, is the intermediate product connecting civil and industrial valves.

2. The product running state LCD screen is visible and has manual and electric control functions.

3. Adopt all-metal gear transmission, with reliable performance output torque, up to 6NM.

4. Adopt double limit of electrical and mechanical, accurate positioning and high consistency.

5. The connection between the actuator and the valve is ISO5211 standard, and the flange type is F03 and F05, which is convenient for the user to match the valve body.

6. The ball valve adopts the floating seal structure, no drop leakage, which is suitable for heavy dirt and long period of no action.

7. Good sealing performance, the protection grade is IP65.

            Operation instructions

            High performance industrial computer kernel, large torque output, can drive DN8-DN32 calibre ball valve;

            Input 4~20mA control, feedback 4-20ma signal;

            Control accuracy: 0.5%~1%;

            Electric actuators have two kinds of working status: automatic state (input signal control switch),
            manual state (key control switch);

            1. In manual mode, no operation for 30 seconds, automatic return to automatic mode, receiving input
            4~20mA signal control;

            2. When the input signal is broken, or the signal is lower than 3mA (the standard is the lowest,
            normal is 4mA), the warning of "OFF" is displayed;

            3. Automatically eliminate the input signal of the input signal below 4mA or greater than 20mA due
            to abnormal reason to stop the valve operation;

            4. In the automatic state, you can check the input signal size at any time (in the form of percentages,
            such as 12mA display is 50%), so as to facilitate on-site debugging;

            5. Press the button 1 to switch "automatic/manual" mode, and the opening displays the flicker when the
            representative switches to manual mode, which can be manually adjusted;Once again press the button 1,
            the opening display stop flicker, switch to automatic mode;

            6. In manual mode, press the button 2 to open the valve, release the key or open the position valve
            to stop automatically;

            7. In manual mode, press the button 3 to close the valve, release the button or close the valve
            to stop automatically.
