The EGR valve is mounted to a spacer between the carb and the intake manifold. It uses a vacuum-operated diaphragm to open the valve, and an internal spring to close the valve when vacuum is released.
Check the following URL for a pic. The "Top view" at the bottom of the page shows what you can see of the EGR diaphragm from above the carb:
You don't have to "remove" it. It is vacuum or electrically actuated (on new cars), so you can just unplug the vacuum hose and plug the hose with a bolt, or unplug the electrical connector. You can leave the EGR fitting open, it receives vacuum by design from the hose, so it won't leak. On computer controlled newer vehicles, unplugging it will cause the check engine light to go on. But it's no biggie, I've put literally 190,000 total miles on (3) different computer controlled cars I've owned in the last 8 years, all with check engine lights on, never missed a beat and ran great- better than with the valve hooked up.
As engines get older, they will tend to run better with EGR disconnected. I had one that had a stalling problem, that went away when I disconnected the EGR. It must have been opening at idle.
