What is the allowable overpressure for a pressure relief valve?
This allowable overpressure is generally 10% for Valves on unfired systems. This margin is relatively small and some means must be provided to assist in the lift effort. Most pressure Relief Valves, therefore, have a secondary control chamber or huddling chamber to enhance lift.
