Danfoss proportional integral valve electric control valve VF+AME55

Danfoss proportional integral valve electric control valve VF+AME55Main technical characteristics of Danfoss electric control valve

Driver section:

1: Danfoss drivers can receive any control signal from 0-20mA, 4-20mA, 0-10v, 2-10v, with an output signal of 0-10v or 2-10v. They have input signal segmentation function and can sequentially control two electric regulating valves with one signal.

2: The drive has a self check function for travel

After the driver is powered on * times, it can automatically detect the size of the valve stroke and correspond it to the corresponding control model.

3: The drive has safety protection function

The driver has a limit position force sensitive switch, which provides overload protection for the motor and can effectively prevent the driver from burning out. The driver has a protective function against wiring errors and will not be damaged due to wiring errors. There is a signal light to display the status of the driver, and any abnormalities can be determined by the status displayed on the signal light.

Other functions of the driver

Valve position display function, allowing for external observation of the valve's opening position

Can change the valve stroke to make the valve's KVS closer to the design requirements

Valve forward and reverse action settings can easily meet the requirements of different working conditions

Manual operation function to ensure normal operation in a power-off state

The driver has 256 steps, making valve positioning more accurate.

Valve body part:

1: The valve body drive shaft seal is designed to be replaceable for easy maintenance;

2: Special valve core design can reduce noise levels;

3: The control ratio of the valve is large, reaching 1:100, which means it has good regulating performance at an opening of 1% or more:

4: Paired with Danfoss drivers, the small closing pressure difference is above 1.5 bar.
