Electronic expansion ball valve EXR… Product features Selection Bereva recommends its sizing software, that is free to download from Bereva web site. Working concept The actuator receives from the superheat control driver a signal of the desired position of the valve and it moves in correspondence to this. The feedback signal is used to indicate the position of the actuator from 0 to 100%. The opening of the ball valve is counterclockwise and closing clockwise.
