The EGR valve recirculates part of the exhaust gases (hence the name) back into the intake. The intent is to give unburned fuel in the exhaust a second chance to be burned, in an effort to reduce pollution. While is does do that, after a fashion, it is an "add-on" rather than a "designed-in" and does not work that well while having significant negative effects, as Zerohour3k has said.
