WebDec 7, 2015 · A bellows failure provides a route for the release of processfluids to the atmosphere via the pressure relief valve bonnet vent. When the relief valveexperiences over- pressure the valve disc will lift to allow process fluid to discharge intothe outlet of the valve. The fluid can then reach the bonnet vent via any holes in thedamaged bellows. WebTypically, if the valve's lift exceeds the minimum, the valve will have a satisfactory capacity.
