Use Google
Select Images
Enter 3 port actuator and look at the pictures
Enter 2 port actuator and look at the images

You will see they are all very similar

Again using Google Images enter 679H340-30L0
and click on image #5 on the right of the top line.

The electronic "head" is removable - a small black button - when pressed in - allows it to be easily removed from the pipework.

Good luck...
