Difficulty Replacing Pressure Relief Valve

I am having difficulty replacing the Pressure Relief Valve on the Guardian Water Purifier. The instructions state the Pressure Relief Valve should be turned 1/3 of a rotation and then carefully removed. However, after several attempts I am unable to remove the Pressure Relief Valve. Does MSR have any suggestions?
