Karl, it is pretty hard to give you any advice when I don't have the foggiest idea what kind of air compressor you have.

The PRV valve may go off if it is failing, or if there is an obstruction in a line between air cylinders... but I really can't help without more information about your air compressor.

Please post more details as a comment here.

Cheers,

Bill
