Zusammenfassung:	A valve system includes a bellows-type pressure relief valve and an attachment assembly. The bellows-type pressure relief valve includes a main housing defining a main chamber, an inlet opening, and an outlet opening, a bonnet housing defining a bonnet chamber and a bonnet vent in the bonnet housing, and a bellows structure defining a bellows chamber fluidly connected to the bonnet chamber. The attachment assembly is coupled to the bonnet vent to selectively plug the bonnet vent. The attachment assembly include a coupling to couple to the bonnet vent, a pressure sensor to detect a pressure in the bonnet chamber, and a vent structure including a vent valve to selectively open in response to an applied force or in response to the pressure sensor detecting a pressure in the bonnet chamber reaching a pressure threshold.
