Most EGR valves must be replaced with factory dealer parts in order to pass state emissions. Aftermarket valves will not pass the test. Keep this in mind when you finally replace it. Sorry I cannot give you details on how to do it.
The typical EGR valve can be cleaned and possibly repaired in some cases. Carbon build up can be scraped and blown out with compressed air.A pinhole in the rubber diaphragm (a common problem)can be fixed using high temperature silicone sealant. Locate the hole with soapy water while blowing into vacuum hose. Clean area with alcohol and let dry. Apply silicone sealant with a toothpick to the hole while sucking on the vacuum hose to draw the sealant into the hole. Let dry overnight. Such a repair can last many years and pass SMOG testing easily, saving the owner hundreds of dollars for parts and labor.
